Lawrenceville Main Street is a nonprofit civic organization that works to improve the downtown area of the historic Village of Lawrenceville, located in the northern end of Lawrence Township, by organizing events such as the Lawrenceville Farmers Market and the Music in Weeden Park summer concert series. The group's goals include preserving the area's history, revitalizing the local economy, improving property values and promoting the village area as a "convenient place to live, shop and work."
Lawrenceville Main Street's office is located in the same building as the nonprofit Lawrence Township Education Foundation.
