- This article is about the Unix-based tracker. For the classic Amiga program, see Ultimate Soundtracker.

SoundTracker is a free tracker for Unix-like operating systems running X Window System. Its user interface resembles Fast Tracker, the classic MS-DOS-based audio tracker. SoundTracker is licenced under the GNU General Public License and it uses GTK+ (version 1, which has been succeeded by version 2) as its widget toolkit. For many years, SoundTracker was one of the very few mature audio trackers available for Unix-like operating systems.
SoundTracker's name is a tribute to the 1987 Amiga program Ultimate Soundtracker which is regarded as the first program of this type.
