Burtonsville is an unincorporated community in Montgomery County, Maryland. It is named after Isaac Burton who bought the land inherited by his siblings, making him the area's major landowner. Burton operated a store at the intersection of Old Columbia Pike road and a road leading to Sandy Spring, which became the center of the growing community. A post office was established in his store in the 1850s, and Burton became the area's first postmaster. Although the area was surveyed and settled as early as 1700, it was only after Burton's 1825 land purchase that the community began to gel. Today, Burtonsville (originally called Burton's) holds an annual festival celebrating its founder, with a parade, games, petting zoos, and other various activities, and small social events all over town. The community continues to center itself around the two original roads, now designated as Maryland Route 198 and US Route 29.
