Jason David Frank (born September 4, 1973) is an American actor and professional mixed martial artist. He is most notable for his career as Tommy Oliver from the Power Rangers franchise.

In July 2019, a crowdfunding campaign for the film Legend Of The White Dragon, including Frank, Johnny Yong Bosch, Jason Faunt, Ciara Hannah, Yoshi Sudarso, Chrysti Ane, and Jenna Frank, was launched on kickstarter.^[3]

Frank originally auditioned for the role of Jason Lee Scott, the Red Ranger, but lost the role to Austin St. John. He auditioned again in 1993, and was cast in the role of Tommy Oliver, the Green Ranger.

Frank was supposed to be the lead character Adam Steele in VR Troopers (originally called "Cybertron") and shot a pilot episode before being called back to Power Rangers. According to both Frank and Brad Hawkins, Hawkins' character was to replace Tommy Oliver originally as the White Ranger on Power Rangers.^[4][5] However, due to Tommy Oliver's popularity with Ranger fans, Frank was brought back, with Tommy Oliver becoming the White Ranger.^[6] Hawkins would take over on VR Troopers. The character Adam Steele was renamed Ryan Steele.

After three seasons, Mighty Morphin Power Rangers transitioned into Power Rangers Zeo. The transition is part of the annual Ranger suit change to match the annual change of the Super Sentai series. Frank's character became the Red Zeo Ranger (also called Zeo Ranger V). The following year in Power Rangers Turbo, his character became the first Red Turbo Ranger. During mid-season, Frank and fellow cast members Johnny Yong Bosch, Nakia Burrise and Catherine Sutherland agreed to leave and were replaced.

After he left the series in 1997, Frank came back to Power Rangers as the Red Zeo Ranger in 2002 for the special 10th anniversary episode, entitled "Forever Red", in Power Rangers Wild Force, which brought back ten former Red Rangers, and reunited him with Austin St. John. He then reprised his role in 2004 in Power Rangers Dino Thunder, as the Black Dino Ranger. During his time as the Black Dino Ranger, Frank was always shown in long-sleeved shirts to cover his tattoos on his arms. This was also the case during "Forever Red" of ‘’Wild Force’’. Being the Black Dino Ranger was a favor to Douglas Sloan.^[7] He has joked that Saban and Disney are "both the same, they're cheap" but that he was impressed with the production crew for Dino Thunder.^[8] Frank reprised his role as Tommy Oliver (who in turn was the Green Ranger for the episode) in the season finale of Power Rangers Super Megaforce.^[9]

Frank has expressed interest in developing a Green Ranger solo series or feature film after an encounter with Stan Lee at a comic book convention.^[10]

On November 13, 2013, "Bat in the Sun" released an episode of "Super Power Beatdown" and featured Frank as the White Ranger against *Mortal Kombat'*s Scorpion. On May 5, 2015, Frank again appeared on "Super Power Beatdown" as the Green Ranger and defeated Ryu from Street Fighter.^[11]

After success with the "Super Power Beatdown" series, Bat in the Sun began developing a web reality series of Frank titled, "My Morphing Life".^[12] As of 2015, the show began airing season 2.

Frank was given a cameo role in the 2017 film Power Rangers, as a citizen of Angel Grove, along side fellow Power Rangers actress, Amy Jo Johnson. In 2018 he reprised his role as Tommy in episode 10 of Power Rangers Super Ninja Steel for the 25th anniversary of Power Rangers.
