The Fort Tejon State Historic Park is a historic site and state park in Lebec, California. Located in the Grapevine Canyon along the Tejon Pass in Interstate 5, the site preserves the site of Fort Tejon.

Fort Tejon was created in 1854 in order to protect the San Joaquin Valley from attacks of Native American tribes and suppress stock rustling. It functioned intermittently from 1854 to 1864. The great earthquake of 1857 was named after the fort, although, the center wasn’t anywhere near it.

Today, the Fort Tejon State Historic Park is operated as a public park by the state. It was listed on the National Register of Historic Places. Civil War and Dragoon life reenactments are commonly held at the site.
