Lathrop is a city located 9 miles (14 km) south of Stockton in San Joaquin County, California, United States. The 2020 United States Census reported that Lathrop's population was 28,701. The city is located in the San Joaquin Valley in Northern California at the intersection of Interstate 5 and California State Route 120.


Lathrop was platted when the railroad was extended to that point. A post office has been in operation at Lathrop since 1871. The city was named for the maiden name of the wife of Leland Stanford. In September 1869, four months after the railheads of the transcontinental railroad met at Promontory, Utah, the completion of the San Joaquin River Bridge at Mossdale crossing at Lathrop actually completed the west coast link.

On August 14, 1889 Chief Justice of California David S. Terry assaulted United States Supreme Court Justice Stephen J. Field, at the train station in Lathrop. Field's bodyguard United States Marshal David Neagle (formerly assigned to Tombstone, Arizona) shot and killed Terry. The events led the United States Supreme Court decision In re Neagle.
