Sofia Larsson Ocklind, professionally known as Soffy O, is a Swedish vocalist, songwriter and electronic musician living in Berlin. She is mostly known from her collaboration with the techno collective stalwarts Toktok which lead to the 2002 critically acclaimed Toktokvs.SoffyO album, with the commercial singles "Missy Queens Gonna Die" and "Day of mine". Toktokvs.SoffyO has toured occasionally ever since and intend to keep doing so.

Soffy O does occasionally pick up the guitar and play the keyboards. This resulted in the project Bathcat: a melange of hypnagogic pop and shoegaze where she involved producer Berend Intelmann and Chris Imler on drums.
