Tulls Corner is an unincorporated community in Somerset County, Maryland, United States.

Tulls Corner started originally from a crossroads store prior to the Revolutionary War and expanded gradually until it reached its height shortly after the end of the American Civil War.

At that time, the settlement consisted of several homes, three or four stores, a post office, shoe shop, blacksmith shop, tannery, and a nearby school and church.

Later a saloon, millinery shop, barrel factory, tomato cannery and other businesses were added.

[2] St. Paul's Protestant Episcopal Church was listed on the National Register of Historic Places in 1990.
