The town of New Wilmington was established in 1797–1798. In 1824, the first house was built and other buildings were soon erected. In 1847 an Amish settlement was established between New Wilmington and Volant. On April 4, 1863, New Wilmington was established as a half-Borough, and on April 9, 1873, it was made a full borough. The population in 1874 was 500. As of the 2000 census, the population had grown to 2,452, which included 1,315 residents and 1,137 college students.

In the fall of 2014, community members led by mayor Sherie Babb, formed the New Wilmington Economic Development Committee. This group was established to encourage not only economic health, but a variety of betterment initiatives around the town.

In January 2016, LIVE New Wilmington, a promotional campaign developed and supported by the New Wilmington Economic Development Committee (EDCOM), was officially launched. The goal of this project is to promote connection and celebration as the residents join in a community that is a hub for artists and quality education, picturesque environment, and caring neighbors. Because of this, the group has chosen to focus on these areas (arts, education, environment, people) as the pillars for nurturing and fostering growth. It is believed that these qualities are unique to the community, deserve to be recognized, and should be given a larger platform for actualization.
