Rock Run United Methodist Church is a one-story building, with stone walls and a slate-covered gable roof, located on a 1.24 acre plot of land at the corner of Craig's Corner Road and Rock Run Road near Level, Maryland, USA, and approximately six miles south of Darlington, Maryland.

It was listed on the Maryland Inventory of Historic Properties in 1977 by the Harford District Commission with code title HA 565.

The founding of Methodism in Harford County, Maryland, can be traced to Francis Asbury during his travels in 1785, when Ms Rachel Barnes Stephenson offered her home as a place of Methodist meetings.

In 1830, he and his wife traveled throughout Harford County on horseback to those who were almost secluded from other religious societies.In 1811, 125 people were members of the Society.

William Stephenson and Mr. Thomas Nathaniel Smith, on the east side of the old Stafford Road (now in the Susquehanna State Park) near a spring.

Due to the ongoing segregation of the area, a balcony was included inside for the use of the local colored people.

The pulpit furniture currently in the chancel was given in the same year and a painting of a scene regarding the three crosses of Calvary was also completed.

It no longer exists.In 1932, shortly after the merger with the Darlington and Thomas Run Methodist Charge, a sesqui-centennial celebration was held.

Four years later, in 1949, the church was redecorated, with new carpet included, and the addition of side doors on the northeast wall.

At the time that the first Rock Run Church was constructed in 1813, the local people decided there was a definite need for a school.

The Stephenson school was built of salvaged boards from the nearby Susquehanna River and when finished was a one-room building with four windows and a loft.
