Marsh Aviation is an aircraft engineering, design, maintenance and re-manufacturing company, situated on East Falcon Drive, at Falcon Field in Mesa, Arizona. The company often works as a sub-contractor to well-known brand-name aerospace companies, discreetly designing and manufacturing components and sub-systems for high-profile programs. The company has also worked on a variety of aircraft programs for governments all over the world.

Founded in December 1961 to convert piston-powered aircraft to turboprop power, the company's first projects involved fitting Rockwell Thrush Commander agricultural aircraft with Garrett AiResearch TPE-331 engines. Later, the firm also re-engined Gulfstream Turbo Cats, Beech Turbo Mentors and Grumman S-2 Trackers with Garrett engines.

The company filed for Chapter 11 bankruptcy in September 2009.{{cite web|last1=Thomason|first1=Art|title=Marsh Aviation files Chapter 11|url=http://archive.azcentral.com/community/mesa/articles/2009/09/24/20090924mr-marshbankrupt0926.html|website=The Arizona Republic|accessdate=December 24, 2016|location=Phoenix, AZ|date=September 24, 2009}}
