Osees is an American rock band formed in San Francisco, California in 1997, now based in Los Angeles, California. Originally the solo recording project of John Dwyer, the band has evolved through numerous line-up and name changes since its founding, with Dwyer serving as the band leader and primary songwriter throughout. The group’s sound draws from a wide variety of influences, including garage rock, krautrock, psychedelia, and folk music. Osees are noted for their prolific recording output, energetic live shows, and whimsical visual aesthetic.

Since 2018, Osees has consisted of multi-instrumentalist John Dwyer, bassist Tim Hellman, drummers Paul Quattrone and Dan Rincon, and keyboardist Tomas Dolas. The group has released twenty-six studio albums, five of which feature the current lineup.
