Thomas Stevens was an American trumpeter, composer, and author.

Sequenza X is a composition for trumpet and piano by Luciano Berio, the tenth in his series of pieces with this title. The work was commissioned by the Los Angeles Philharmonic for Thomas Stevens, and premiered by him on November 19, 1984. The piece is dedicated to Ernest Fleischmann, managing director of the Los Angeles Philharmonic from 1969 to 1997, who convinced Berio to write a Sequenza for trumpet, despite years of resistance to the idea. Stevens received the music only nine days before the premiere.
