Frehley's Comet was an American rock band formed and led by ex-Kiss lead guitarist Ace Frehley. The group released two studio albums and one live EP before Frehley left the band to release his 1989 solo album, Trouble Walkin'.

The band name was a pun of a pun; Bill Haley & His Comets was a 1950s Rock-n-Roll band that derived its name as a pun of the typical mispronunciation of Halley's Comet (properly pronounced as "Hal-lee", rhymes with "valley", but commonly mispronounced as "Hay-lee"), a comet which orbits the Sun near Earth about every 75 years. It also helped people pronounce Frehley's name properly to connect it to the common mispronunciation of Halley as "Hay-lee", as in "Fray-lee" vs. the common mispronunciation as "Free-lee".
