Frank J. Lapidus is a fictional character on the ABC television series Lost played by Jeff Fahey. Frank is introduced in the second episode of season four as a pilot hired on a mission to the island where Oceanic Flight 815 crashed. He aids the survivors of the crash against mercenary Martin Keamy (Kevin Durand) and helps to rescue a group who become known as the Oceanic Six. Three years later, Frank encounters the group again while working as a commercial airline pilot. His plane lands back on the island, and he is forcibly taken in by a group of his passengers headed by Ilana (Zuleikha Robinson) and Bram (Brad William Henke), who are working for the island's highest authority figure Jacob (Mark Pellegrino). In the series finale, he ultimately escapes the island with a few of his fellow inhabitants.

Frank's name was created by co-executive producer Edward Kitsis, who had been pitching the name "Lapidus" for years and had also used it for an unseen character in the episode "Exposé". Fahey was the producers' first choice for the role, which was developed to suit his personality. As a result of the 2007–2008 Writers Guild of America strike, Frank's role in the first half of season four was diminished, and some planned storylines were carried over into the fifth season. Frank's introduction, along with the three other new characters from the freighter introduced in season four, was well received, as was his return in season five. Lost executive producer Damon Lindelof confirmed in an interview that Lapidus would be a series regular for the show's sixth and final season.
