Rocco Katastrophe (Rocco Kayiatos), also known by just Katastrophe, is a San Francisco-based rapper and producer. In past albums, he went by just Katastrophe, but for his latest album Second Hand Emotion, released June 26, 2012, he chose to change to Rocco Katastrophe.

Kayiatos began competing in poetry slams in 1997. After winning the 1998 Youth Speaks poetry slam, he went on tour with Sister Spit's Rambling Road Show tour. By age 19 he had poems on four compilation cds. He is widely credited as the first openly transgender singer in the hip-hop genre and he often incorporates his being a trans man in his work.

He started making beats as Katastrophe in 2002. He raps about lives lived outside the mainstreams of education, gender, and culture. He uses his struggle as a trans man and his contested place in contemporary queer and hip hop culture to discuss larger issues of community, space, privilege, sex, and self-worth.
