Lockhart Township is a township in Norman County, Minnesota, United States. The population was 63 at the 2000 census.

Lockhart Township was organized in 1882, and named for Charles Lockhart, the owner of Lockhart Farm. He was connected with the Standard Oil Company and died in 1908. In 1901, the Lockhart Farm was sold and split up into smaller farms and many farmers from Illinois came here to settle. About this time, the village of Lockhart began to take shape. The depot had been located at Rolette, a small station 1.5 miles north of the present site of Lockhart. Rolette was named for Joseph Rolette who served in the Minnesota Territorial Legislature from 1851-1858. It was an exciting event when the elevator at Rolette was moved to Lockhart. It took two months. They used a cable and winch, used a horse to wind up the cable, moved the building a short distance, then staked it out again and so on. August Maas, a German immigrant opened a general store in Rolette in 1886 where he was also the postmaster. In the fall of 1901 he moved the store South to Lockhart.
