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.
