After purchasing land from the local natives, the first settlers established themselves around South Salem. The town was formed as "Salem" in 1747. By 1790 the town assumed its current dimensions as lands were removed for other towns. The name changed to South Salem in 1806. John Lewis, a financier, requested that the town be given his name and established a fund for the town, though he did not follow through on his promise of a railroad link. An abundance of natural open space, Dry-stone walls and elegant Colonial mansions are dominant features.

Lewisboro has had two noteworthy historical characters. Sarah Bishop was the hermit of West Mountain. Apparently mistreated by British soldiers at the time of the Revolutionary War, she retreated to a solitary life in the Lewisboro area. A spot known as "Sarah Bishop's Cave" is on the hill on the north side of Lake Rippowam, near Mountain Lakes Camp. The second historical character appeared around the time of the Civil War. The Leatherman was a wanderer who got his name from homemade leather garments. He is frequently mentioned as being in Lewisboro in the middle of the 19th century. He followed a route past homes that would offer him a meal and reappeared at the same doorsteps for 25 years. One of the hiking destinations in Ward Pound Ridge is to the Leatherman's cave, reportedly one of his more frequent homes. In 1987, a 10k trail race called "The Leatherman's Loop" was started to honor his legacy and continues every spring at the Ward Pound Ridge Reservation.

The Mead Memorial Chapel was listed on the National Register of Historic Places in 1999.

The east town line is the border of Ridgefield, Connecticut and Wilton, Connecticut, while the southern border is the town of New Canaan, Connecticut. Interstate 684 passes near the west side of the town. The town's unusual chevron shape is partly the result of The Oblong, created during the resolution of the boundary dispute between Connecticut and New York.

According to the United States Census Bureau, the town has a total area of 29.1 square miles (75 km), of which 27.9 square miles (72 km) is land and 1.3 square miles (3.4 km), or 4.36%, is water.

There are 7 lakes in the town of Lewisboro. Lake Waccabuc, Lake Oscaleta, and Lake Rippowam are interconnected and are collectively known as the Three Lakes, and are natural (not man-made) lakes. Lake Waccabuc is the largest and most well-known of these, and the area of town named after it has a separate post office. Lake Oscaleta and Lake Rippowam are also called the Twin Lakes, probably because of Twin Lakes Village, a development which runs between them. The other lakes in town are Lake Truesdale, Lake Katonah, Lake Kitchawan, and Timber Lake. Recognizing the importance of the lake communities in the town, in 2007 a Lakes Committee was formed by the Town of Lewisboro.

Additionally, there are a number of reservoirs in the town of Lewisboro, utilized by cities such as Norwalk, Connecticut.
