Sebastian Currier (born March 16, 1959) is an American composer of music for chamber groups and orchestras.

His compositions include Crossfade, written for two harps, and Microsymph, described as a "30-minute symphony compressed into 10 minutes."

In October 2005, members of the Berlin Philharmonic performed an entire evening of his works, including the premiere of Remix.

Violinist Anne-Sophie Mutter has recorded Currier's Aftersong, which the composer dedicated to her.

On March 12, 2013, the Institute for Advanced Study at Princeton announced the appointment of Currier as Artist-in-Residence, his term to begin on July 1, 2013.
