Dart is an unincorporated community in Washington County, in the U.S. state of Ohio.
A post office called Dart was established in 1905, and remained in operation until 1984. According to tradition, the townspeople were searching for a suitable name when they saw a bird flying "like a dart".
Dart had the Lawrence Elementary School until it closed around 2014 due to low enrollment.
