Congo is a village in Douglass Township, Montgomery County, Pennsylvania, United States.

The village was named Cedarville until the 1880s, when the US Post Office decided to rename it due to the existence of at least three other Pennsylvania post offices with "cedar" in their names.

The Congo Basin was in the news at the time due to conflicting European claims and measures to settle them.

While the Congo post office closed around 1925, the name has remained with the community ever since.
