In 2003, Rudd married Julie Yaeger, whom he met shortly after working on Clueless in his publicist's office, where she was employed.
They have two children: a son and a daughter.
They live in Rhinebeck, New York.

Rudd is a fan of MLB's Kansas City Royals and of the NFL's Kansas City Chiefs, for whom he narrated the 2007 season of HBO's Hard Knocks.

Rudd received a star on the Hollywood Walk of Fame on July 1, 2015.
He unveiled the 2,554th star on the mile-long strip of plaques on Hollywood Boulevard.
At the occasion Rudd said, "I remember being a kid and walking this boulevard and reading the names and thinking about what so many other millions of people thought about, which is, you know, 'Who's that?'"

Rudd is a supporter of the Stuttering Association for the Young (SAY), a nonprofit organization dedicated to helping young people who stutter.
He hosted the organization's 6th Annual All-Star Bowling Benefit on January 22, 2018.
Rudd told Vanity Fair that he became an advocate for stuttering awareness after portraying a character who stutters in a play.
Rudd is also a founder of the charity The Big Slick, a celebrity studded sports-focused event held in Kansas City every June to support the works of Kansas City's Children's Mercy Hospital.

Since 2014, Rudd and fellow actor Jeffrey Dean Morgan have been co-owners of Samuel's Sweet Shop, a candy store in the town of Rhinebeck, New York, that they saved from being closed after the previous owner, a friend of theirs, died suddenly.
