Los Angeles State Historic Park (LASHP) is a state park unit in development within the Chinatown neighborhood of Los Angeles. Also known as the Cornfield, the former brownfield consists of a long open space between Spring Street and the tracks of the Metro Gold Line. Located outside the main commercial and residential area in the northeast portion of Chinatown, the area is adjacent and southeast of Elysian Park neighborhood.

This former site of the Southern Pacific Transportation Company's River Station (1876−1901) is considered the "Ellis Island of Los Angeles" where new arrivals from the east first disembarked. Corn leaking from train cars and sprouting along the tracks gave rise to the nickname The Cornfield. The 32-acre (13 ha) site was established as a California state park in 2001. The parks grand opening was April 22, 2017.
