The Outpost is an opera or operetta by the composer Hamilton Clarke with a libretto by A. O'D. Bartholeyns. The story is an adaptation of the Singspiel Der vierjährige Posten by Theodor Körner with music by Franz Schubert. Both the score and the libretto appear to be lost, but there survives a copy of a fantasia for flute and piano, based on airs from the piece, and so the vocal score may have been published.
