It was Bray who platted out the southeast corner of his land and sold the lots to newcomers traveling into the mid-state wilderness. They were soon followed by Joseph Kilbourne, who took out land for his brother-in-law, Freeman Bray. The first settlers near the current Village of Okemos (to the south of the former Pine Lake) were Sanford Marsh and his wife who built their cabin in 1839. Currently, the Village of Haslett is located at the south side of Lake Lansing. An amusement park was introduced and enjoyed immense popularity into the mid-20th century. During the late 19th century, the lake became known as a local vacation area served by an 'interurban trolley' which ran from the City of Lansing to the resort on the south side of the lake. The lake was later the site of a Spiritualist Meeting Camp led by John Haslett. The earliest settlers located at Pine Lake (now Lake Lansing) and made use of the numerous stands of pines to build their cabin. In November 1836 Obed Marshall purchased 180 acres (73 ha) of land near present-day Haslett. Meridian Township was first settled by pioneers in 1836.

The township contains the unincorporated communities of Haslett and Okemos. The township is named after the Michigan meridian, which comprises the eastern border of the township.

As of the 2020 census, the township had a population of 43,916.
