Dwight Twilley (born June 6, 1951, Tulsa, Oklahoma) is an American pop/rock singer and songwriter, best known for his band's 1975 hit single "I'm on Fire."

Twilley and Phil Seymour met in 1967 at a theater where they had gone to see The Beatles' A Hard Day's Night, and soon began writing and recording together. They continued their partnership over the next several years under the name "Oister."

Twilley and Seymour signed with Shelter Records in 1974 as "The Dwight Twilley Band." Their first single, "I'm on Fire," reached #16 on the charts in 1975 with relatively no promotion. During an appearance on American Bandstand, the band played what was to be the follow-up single, "Shark." The success of the film Jaws, however, caused the label to reject the single to keep the group from being perceived as a cash-in novelty act. This was just the beginning of bad luck that would plague the group from that point on. Their follow-up single and completed album went unreleased for 18 months due to label problems, and a second album recorded in England was left unreleased. The belated follow-up single, "You Were So Warm," failed due to distribution problems. When the group's album "Sincerely" was finally released in 1975, it failed as well. Seymour and Twilley befriended the likeminded Tom Petty and contributed backing vocals on several of his tracks. Petty repaid the favor for their second album, "Twilley Don't Mind," for Arista Records in 1977 -- another commercial disappointment. Seymour left the band the following year, pursuing a brief solo career until he died of lymphoma in 1993.

Twilley continued as a solo act, releasing "Twilley" for Arista in 1979 and "Scuba Divers" for EMI America in 1982. He finally found success again with the album "Jungle" in 1984, which included Twilley's second hit single "Girls." His 1986 followup album "Wild Dogs" went unnoticed on its CBS Records. In addition, Twilley recorded an album in 1980, Blueprint, that remains unreleased and contributed one track to the 1992 Wayne's World soundtrack, "Why You Want to Break My Heart." In 1993, DCC released "The Great Lost Twilley Album," which collected a fraction of the "hundreds" of early unreleased songs Twilley and Seymour had recorded. Two newly recorded songs appeared on the best-of collection "XXI" (The Right Stuff) in 1996, and in 1999, Twilley released both another rarities collection, "Between the Cracks, Vol. 1 (Not Lame Archives)," and his first new album in 13 years, "Tulsa" (Copper). In 2001, Twilley released "The Luck" (Big Oak), an album he had actually completed in 1994. The seasonal EP "Have a Twilley Christmas" (dmi) appeared in 2004, followed by Twilley's ninth studio album, "47 Moons," in 2005.
