In the 1994 film Forrest Gump, Jenny reveals that she wants "to be a famous folksinger. Like Joan Baez." A Baez tour poster can be seen above her dorm room bed in the same scene. A live Baez version of "Blowin' in the Wind" is featured on the film soundtrack.
In the 1991 Vietnam War-era drama Dogfight, a copy of Baez's debut album can be seen on the protagonist's nightstand beside her bed. Baez's recording "Silver Dagger", appearing on the soundtrack, plays during a pivotal scene in the film.
Cartoonist Al Capp, creator of the comic stripLi'l Abner, expressed his right-wing views during the 1960s by satirizing Baez as a folk singer he called "Joanie Phoanie". Joanie was an unabashed communist radical who sang songs of class warfare – while hypocritically traveling in a limousine and charging outrageous performance fees to impoverished orphans.  Capp had this character singing bizarre songs such as "A Tale of Bagels and Bacon" and "Molotov Cocktails for Two". Although Baez was upset by the parody in 1966, she admits to being more amused in recent years. "I wish I could have laughed at this at the time", she wrote in a caption under one of the strips, reprinted in her autobiography. "Mr. Capp confused me considerably. I'm sorry he's not alive to read this, it would make him chuckle," (from And A Voice To Sing With, 1987).
The 1972 comedy album National Lampoon's Radio Dinner includes a Baez parody, "Pull the Triggers, Niggers" (deliberately misspelled as "Pull the Tregroes" on the LP's outside liner notes), performed by Baez sound-alike Diana Reed. The satiric song made specific reference to Baez's ex-boyfriend Bob Dylan's defense of Black Panther and convicted murderer, George Jackson.
In a 2003 episode of the HBO series Six Feet Under, a character, after watching the film Silent Running, comments "I've always loved Joan Baez." Baez's song "Rejoice In The Sun" can be heard in the background.
Baez has been lampooned multiple times on Saturday Night Live, by comedienne Nora Dunn. One skit features a game show entitled "Make Joan Baez Laugh!" where a dour Baez is ushered onstage while celebrity guests try their hand at getting her to a crack a smile.
