It's a Bikini World is a 1967 American musical comedy film starring Tommy Kirk, Deborah Walley and Bobby Pickett. The film features cameos by the music groups the Gentrys, the Animals, Pat & Lolly Vegas, the Castaways and R&B girl group the Toys. Featuring a pro-feminist plotline, it is the only film in the beach party genre to be directed by a woman (Stephanie Rothman).

This film, along with Catalina Caper (which also starred Tommy Kirk), is among the last of the beach party films. The mainstay of the once-popular genre was the series of films by American International Pictures (AIP), starting with the surprise hit Beach Party in 1963 and ending with The Ghost in the Invisible Bikini (a box-office flop) in 1966.

Although AIP picked up distribution, It's a Bikini World was not an AIP film. It was produced and originally distributed by Trans American Films under the title The Girl in Daddy's Bikini. A new 35-mm print with this title was screened at the American Cinematheque in Hollywood on August 1, 2009.
