Goat Canyon Trestle is a wooden trestle in San Diego County, California. At a length of 597–750 feet (182–229 m), it is the world’s largest all-wood trestle. Goat Canyon Trestle was built in 1933 as part of the San Diego and Arizona Eastern Railway, after one of the many tunnels through the Carrizo Gorge collapsed.

The railway had been called the “impossible railroad” upon its 1919 completion. It ran through Baja California and eastern San Diego County before ending in Imperial Valley. The trestle was made of wood, rather than metal, due to temperature fluctuations in the Carrizo Gorge. By 2008, rail traffic stopped using the trestle.

Designed by Chief Engineer of the San Diego and Arizona Railroad, Carl Eichenlaub, it was built to common standard drawing CS-33 standards. The trestle was built in response to the collapse of Tunnel 15. According to the original plans, the trestle would be 633-foot (193 m) long, and 186-foot (57 m) high. Construction began in 1932.
