Stockton was platted in 1856. The city was named after J. B. Stockton, an early landowner. A post office was established at Stockton in 1855, and remained in operation until 1959. The city has one property listed on the National Register of Historic Places, the 1859 Trinity Episcopal Church.
The Winona and St. Peter Railroad was founded in 1861 in Winona, Minnesota. The first 11 miles from Winona to Stockton were completed by the end of 1862, making it the second operational railroad in Minnesota, after the St Paul and Pacific Line from St. Paul to St. Anthony Falls. In 2009, the city expanded, annexing the Garvin View Estate subdivision. The subdivision brought municipal water to the town.
