Jimtown is an unincorporated community in Sussex County, Delaware, United States.

The area around Jimtown was settled by whites as early as the 1690s when the court at either Lewes or Sussex County[a] granted a petitioner land on Bundick's Branch to build a mill, so long as he "build the mill within fifteen months and [...] attend and minde the same and grind the grain well and in due course as it is brought thither without respect of persons, at the eighth part tolle for wheat and the sixth part tolle for Indian corne.

In the early 20th century, the site was the location of a "colored" schoolhouse[4] during an era when segregation was still legal in Delaware.

[2] Residents in Jimtown clashed again with the owners of the neighboring subdivision of Coastal Club near Lewes in 2014 over the issue of streetlights, sidewalks, and sewer connections in the community; the plan at that time was to offer Jimtown residents sewer and streetlights connecting to the new subdivision.

[6] In 2018, a 49-lot subdivision adjacent to Jimtown, named Marine, was approved by Sussex County officials.
