Kira Roessler (born June 12, 1961) is an American musician who was the bass guitarist for the influential hardcore punk band Black Flag from 1983 to 1985.

Born in New Haven, Connecticut,[1][2] Roessler lived there until age eight when her family moved to the Caribbean until she was eleven[2] and thereafter in California, mostly in Los Angeles.

[4][5] Vocalist Henry Rollins later reported that Greg Ginn, Black Flag's leader, guitarist and primary songwriter, had grown frustrated with Dukowski's failure to progress as a musician beyond the band's hardcore punk roots and was drawn to Roessler's more nimble and sophisticated playing.

[6] Roessler was majoring in applied engineering at UCLA, and Black Flag's subsequent tours were scheduled around her classes—a condition of her joining the band.

[9] On August 13, 2021, on the Protonic Reversal podcast,[10] Kira revealed that an album of solo material would be released on October 19 on Kitten Robot records.

She has worked on productions including Confessions of a Dangerous Mind (2002), Under the Tuscan Sun (2003), and The Twilight Saga: New Moon (2009), and has also appeared onscreen in the documentaries We Jam Econo: The Story of the Minutemen, American Hardcore and What Drives Us .
