Plainsburg, California

Plainsburg (formerly, Plainsberg and Welch's Store) is an unincorporated community in Merced County, California. It is located 4 mi west of Le Grand, at an elevation of 220 feet (67 m).

Plainsburg was said to be a thriving farming center in the nineteenth century. It had several businesses and was legally incorporated for a time. The town declined when it was bypassed by the Southern Pacific Railroad to the west and later the Santa Fe Railroad to the east. A grocery store remained as of 1992; the cemetery and elementary school are still present today.

A post office operated at Plainsburg from 1869 to 1907.
