Matt Ouimet, the former president of the Disney Cruise Line, was promoted to assume leadership of the Disneyland Resort in late 2003.
Shortly afterward, he selected Greg Emmer as Senior Vice President of Operations.
Emmer was a long-time Disney cast member who had worked at Disneyland in his youth prior to moving to Florida and held multiple executive leadership positions at the Walt Disney World Resort.
Ouimet quickly set about reversing certain trends, especially concerning cosmetic maintenance and a return to the original infrastructure maintenance schedule, in hopes of restoring Disneyland's former safety record.
Similarly to Disney himself, Ouimet and Emmer could often be seen walking the park during business hours with members of their respective staff, wearing cast member name badges, standing in line for attractions, and welcoming guests' comments.
In July 2006, Ouimet left The Walt Disney Company to become president of Starwood Hotels & Resorts Worldwide.
Soon after, Ed Grier, executive managing director of Walt Disney Attractions Japan, was named president of the resort.
In October 2009, Grier announced his retirement, and was replaced by George Kalogridis.

The "Happiest Homecoming on Earth" was an eighteen-month-long celebration (held through 2005 and 2006) of the fiftieth anniversary of the Disneyland Park, also celebrating Disneyland's milestone throughout Disney parks worldwide.
In 2004, the park underwent major renovations in preparation, restoring many attractions, notably Space Mountain, Jungle Cruise, the Haunted Mansion, Pirates of the Caribbean, and Walt Disney's Enchanted Tiki Room.
Attractions that had been in the park on opening day had one ride vehicle painted gold, and the park was decorated with fifty Golden Mickey Ears.
The celebration started on May 5, 2005, and ended on September 30, 2006, and was followed by the "Year of a Million Dreams" celebration, lasting twenty-seven months and ending on December 31, 2008.

Beginning on January 1, 2010, Disney Parks hosted the Give a Day, Get a Disney Day volunteer program, in which Disney encouraged people to volunteer with a participating charity and receive a free Disney Day at either a Disneyland Resort or Walt Disney World park.
On March 9, 2010, Disney announced that it had reached its goal of one million volunteers and ended the promotion to anyone who had not yet registered and signed up for a specific volunteer situation.

In July 2015, Disneyland celebrated its 60th Diamond Celebration anniversary.
Disneyland Park introduced the Paint the Night parade and Disneyland Forever fireworks show, and Sleeping Beauty Castle is decorated in diamonds with a large "60" logo.
The Diamond Celebration concluded in September 2016 and the whole decoration of the anniversary was removed around Halloween 2016.

Disneyland, along with Disney California Adventure, closed indefinitely starting March 14, 2020 in response to the coronavirus pandemic.
After nearly four months of closure, Downtown Disney reopened on July 9, 2020.
The parks had been scheduled to reopen on Disneyland's 65th anniversary on July 17, 2020, but due to rising cases in California, the parks' reopening was once again postponed.
