Lync was a 1990s post-hardcore band from Olympia, Washington.

Formed in 1992, Lync was composed of vocalist/guitarist Sam Jayne, bassist/vocalist James Bertram and drummer Dave Schneider. Lync's distinctive sound of distortion, cryptic lyrics, and irregular tuning created a chaotic, visceral sound which drew comparisons to Fugazi, Unwound, Hush Harbor, The Fall, and Drive Like Jehu.
