I ♥ Huckabees (known usually as I Heart Huckabees but also as I Love Huckabees) is a 2004 American philosophical comedy film from Fox Searchlight. It was produced and directed by David O. Russell, who co-wrote the screenplay with Jeff Baena.

The film stars Jason Schwartzman, Dustin Hoffman, Lily Tomlin, Jude Law, Isabelle Huppert, Mark Wahlberg and Naomi Watts.

Albert Markovski (Schwartzman) is a young man who heads the local chapter of an environmental group, the "Open Spaces Coalition." One of their current projects is an attempt to stop the building of a new Huckabees store, a chain of "big-box" department stores. Albert is a rival of Brad Stand (Law), a shallow power executive at Huckabees. Brad infiltrates Open Spaces and charismatically displaces Albert as the leader. Dawn Campbell (Watts) is Brad's live-in girlfriend and the face and voice of Huckabees; she appears in all of the store's commercials.

After seeing the same conspicuous stranger three times, Albert contacts two existential detectives, Bernard and Vivian Jaffe (Hoffman and Tomlin). The detectives offer Albert their optimistic brand of existentialism—they name it universal interconnectivity (which has some tenets of romantic and transcendentalist philosophies)—and spy on him, ostensibly to help him solve the coincidence. Bernard and Vivian introduce Albert to Tommy Corn (Wahlberg), an obsessively anti-petroleum firefighter. Tommy is assigned to Albert as his Other.

Mary Jean "Lily" Tomlin (born September 1, 1939) is an American actress, comedian, writer, and producer. Tomlin has been a major force in American comedy since the late 1960s when she began a career as a stand up comedian and became a featured performer on television's Laugh-in. Her career has spanned television, comedy recordings, Broadway, and motion pictures, enjoying acclaimed success in each medium. She has won many awards including Tony Awards, Emmy Awards, and a Grammy Award and has also been nominated for an Academy Award. Tomlin's humor is often sharp and insightful in the traditions of standup comedians, but also frequently endearing, slightly wacky, and generally quite "family friendly" in the tradition of television comediennes such as Lucille Ball, Carol Burnett, and Eve Arden.

Tomlin was born in Detroit, Michigan, the daughter of Lillie Mae (née Ford), a housewife and nurse's aide, and Guy Tomlin, a factory worker. Tomlin's parents were Southern Baptists who moved to Detroit from Paducah, Kentucky, during the Great Depression. She is a 1957 graduate of Cass Technical High School. Tomlin attended Wayne State University, where her interest in the theater and performing arts began. After college, Tomlin began doing stand-up comedy in nightclubs in Detroit and later in New York City. Her first television appearance was on The Merv Griffin Show in 1965.

In the early 1980s, Brion and musician/producer Bill Murphy began a writing collaboration in New Haven, Connecticut.

The recordings had much critical acclaim, but little commercial success, and the trio eventually disbanded.
