Kilpatrick Audio is a Canadian electronic instrument maker based in Montreal, founded in 2008 by Andrew Kilpatrick. The company designs and builds standalone synthesizers, Eurorack-format modules, and performance tools, with Kilpatrick handling electronics and software design alongside QP Tharmviboonsri, who manages graphic design and business operations.

The brand is best known in the modular synthesis community for products like the K4815 Pattern Generator, the CARBON sequencer and performance system, the REDOX stereo reverb, and the SQSD (Sextuple Quadraphonic Spatial Director). Earlier products include the PHENOL patchable analog semi-modular synthesizer and the proprietary Kilpatrick Format modular system, which combined ideas from traditional large-format modular synths with new design approaches.

Kilpatrick Audio's catalog leans toward unconventional, performance-oriented designs rather than clones of vintage gear, and the company also produces accessories such as the Super Skiff Eurorack enclosures, the KMIDI interface, and a Buchla-compatible Dual Boat power system. It maintains a presence in the open-source software world through the Kilpatrick-Toolbox modules for VCV Rack.

Kilpatrick Audio has 3 products cataloged on Equipboard, including Modular Synthesizers. Their gear is featured by 4 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Richard Devine, Stephin Merritt, and Dntel.
