Arts and culture
Wellesley's Wonderful Weekend
Each year the weekend before Memorial Day, the town sponsors the annual Wellesley's Wonderful Weekend, which includes the annual veterans' parade and fireworks. On May 18, 2008, The Beach Boys performed in a concert on the Wellesley High School athletic fields in front of an estimated 10,000 town residents and fans. The funds for the performance, an estimated $250,000, were made as a gift by an anonymous donor and lifelong fan of the band.

Wellesley Symphony Orchestra
The Wellesley Symphony Orchestra presents classical, pops, and family concerts at Mass Bay Community College at its Wellesley campus.

Religious institutions
The town of Wellesley is home to several religious institutions. Wellesley contains two Jewish institutions including Temple Beth Elohim and the Wellesley Chabad Center. Predominantly Christian Wellesley contains many churches, including Wellesley Congregational Church, St. Andrew's Episcopal Church, St. Paul's Catholic Church, Christ Church United Methodist, Wellesley Hills Congregational Church (also known as The Hills Church), First Church of Christ, Scientist, St. John the Evangelist Catholic Church, the Metrowest Baptist Church, Milestone Wellesley, and Unitarian Universalist Society of Wellesley Hills, and Wellesley Friends Meeting (Quakers).

Horticulture
The Wellesley College campus includes greenhouses and the H. H. Hunnewell Arboretum. This is not to be confused with the neighboring private H. H. Hunnewell estate. The Elm Bank Horticulture Center is home to the Massachusetts Horticultural Society. Although the entrance is in Wellesley, access is over a small private bridge over the Charles River, so Elm Bank is therefore in the neighboring town of Dover.

Historic district
The town designated Cottage Street and its nearby alleys as the historic district in its zoning plan. Most houses in this district were built around the 1860s and qualify as protected buildings certified by the town's historic commission.

Recent construction
The town's historic 19th-century inn was demolished to make way for condominiums and mixed-use development in 2006. The Wellesley Country Club clubhouse, which is the building where the town was founded, was demolished in 2008, and a new clubhouse was built. The town's pre-World War II high school building was torn down and replaced with a brand new high school finished in 2012. The entire 1960s-style Linden Street strip-mall has been replaced by "Linden Square"—a shopping district that includes a flagship Roche Bros. supermarket, restaurants, cafes, clothing stores, along with a mixture of national chains and local shops.

Library
Wellesley opened its new Free Library building in 2003, which is part of the Minuteman Library Network.  Due to the structure of budget override votes and perhaps the size of the new main branch of the library, the two branch libraries—one in Wellesley Hills, which was purpose-built to be a branch library in the 1920s, another in Wellesley Fells—closed in the summer of 2006. The branch libraries reopened in September 2008. The main library branch near Wellesley Square underwent a major interior renovation in 2021.

Government
The town government has been run by town meeting since the town's founding. Since Proposition 2½ limited property tax increases to 2.5% per year in 1980, the town has had to ask residents for a number of overrides to maintain funding for certain programs. Although the main 2005 override passed, a simultaneous supplemental override to preserve certain specific programs and services failed by 17 votes. The 2006 override passed with a large majority. Wellesley also receives funding from the state government. Local roads have been repaved several times in the 1990s and 2000s.
The town is part of the Massachusetts Senate's Norfolk, Bristol and Middlesex district.
On December 18, 2014, Wellesley College and the Town of Wellesley announced that the College's Board of Trustees had chosen the town's $35-million bid for the purchase of 46 acres of land adjacent to its campus. Under this agreement, at least 50% of the North 40 property will be preserved in perpetuity as open space. A special town meeting in January 2015 resulted in a near-unanimous vote in favor of the purchase, and in March 2015, 80 percent of residents that cast votes at the Town election, voted to approve the purchase.

Reducing carbon footprint
In 2009 the town established the Municipal Energy Efficiency Committee (MEEC) made up of representatives from various town departments, to develop and evaluate municipal policies to reduce energy use.
In 2010 Wellesley's Sustainable Energy Committee (SEC) was formed by Town Meeting. The committee's primary objective was a 10% town-wide reduction in Wellesley's carbon footprint and 20% reduction in carbon footprint for all municipal departments by the end of 2013. In 2014 Town Meeting voted to support a new goal of 25% reduction by 2020 using 2007 as the base year. The committee is responsible for Wellesley's adoption of the Massachusetts Stretch Building Code approved by Town Meeting effective January 2012.In 2013, the committee organized Wellesley's Green Collaborative, a group of organizations that are concerned about environmental issues in Wellesley and beyond. Dozens of like-minded organizations are represented including the Natural Resources Commission, a five-member elected board of town residents; Wellesley Conservation Council, a private, non-profit, land trust and conservation education organization incorporated in 1958; and Sustainable Wellesley, a group of volunteers who encourage sustainability in Wellesley and the surrounding area through events, education, and action.
In 2014 the Sustainable Energy Committee served to double participation in the town's POWER TO CHOOSE program and organized the "More POWER TO CHOOSE" solar program.

Natural resources protection
Wellesley is the longest running Tree City USA community of any city or town in Massachusetts. Wellesley's Tree Bylaw became effective July 1, 2011, requiring property owners to protect certain trees and critical root zones during construction projects, and replace trees that are cut down or donate money to a special tree fund. The town's Natural Resource Protection (NRP) Development bylaw, approved by Town Meeting in 2013, applies to any subdivision generating five or more lots. This bylaw requires a minimum of 50% of the property be preserved as open space in exchange for reduced lot sizes without increasing density.
Established in 1979, Wellesley has a unique elected Natural Resources Commission (NRC) bearing the statutory authority and responsibility of Park Commissions, Conservation Commissions, Tree Wardens, Town Forest Committees, and Forestry and Pest Control Officers. The commission maintains Wellesley's two Community Gardens and maintains a trail network that includes 26 miles of marked trails interconnecting open spaces and conservation lands for walking, dog walking, jogging, bicycling, cross-country skiing, and more.
In 2001 the commission, in collaboration with the Health, Public Works and School department, developed a pesticide awareness program resulting in an Organic Pest Management Policy governing pesticide use on all town-owned property.
In 2003 the commission created the Preservation Master Plan for Fuller Brook Park in collaboration with Wellesley's Department of Public Works. This major restoration project was completed in 2017. In 2009, the commission launched the Green Wellesley Campaign advocating for sustainability by raising awareness and promoting increased environmental action. That campaign has been renamed the Grow Green Wellesley initiative, which promotes earth-friendly lawn and landscaping practices.

Education
On the Massachusetts Comprehensive Assessment System test, the district regularly scores higher than the state average. The school system also contains a middle school and seven elementary schools (Bates, Upham, Schofield, Fiske, Hardy, Hunnewell, and Sprague). Wellesley includes a primary and secondary school which are Wellesley Middle School (also known as Wellesley Junior High) and Wellesley High School, respectively; and are the home of the Raiders.The town contains a private elementary school, Tenacre Country Day School, one private Catholic elementary school (St. John the Evangelist) and a preparatory school for girls, Dana Hall School. Also, the Wellesley A Better Chance outfit started in the early 1970s brings promising young women from underserved areas into town to attend Wellesley High School and live nearby.Wellesley also contains the main campus of three colleges: Wellesley College, a women's liberal arts college, Massachusetts Bay Community College, a two-year public college, and Babson, a business college.

Green Schools
Wellesley Green Schools was established in 2006. The No Idling Campaign received an Excellence in Energy and Environmental Education Award from the state of Massachusetts in 2014.
The town's new high school opened in February 2012 and includes such elements as green vegetated roof, geothermal heat pump and Solar thermal cooling, Solar Photovoltaic system, and rainwater recovery systems.

Media
Events of significance to members of the Wellesley community are recorded in two local news publications: The Wellesley Townsman has been published since 1906, and The Swellesley Report since 2005. Both are available online and digitized copies of the paper-based Townsman are available from the Wellesley Free Library.
