Lake Township is a township that is located in Luzerne County, Pennsylvania, United States. It is part of the Back Mountain, a 118-square mile region in northern Luzerne County. The population was 1,994 at the time of the 2020 census.

The first white man who lived in modern-day Lake Township was Matthew Scouten (in the 1790s). Hollenback & Urquhart would later own much of the territory, and was responsible for building the first sawmill in 1839 and the first gristmill in 1840. Every mill belonging to Hollenback & Urquhart was later transferred over to the Hoffman Lumber Company. At the time, due to the abundance of trees, the lumber industry was one of the major employers in the region.

Lake Township was formed in 1841 from territory taken from Lehman and Monroe Townships. It was named after Harveys Lake, which was originally part of the township. In 1842, Wyoming County was formed and the county line cut off a portion of Lake Township, which was given back to Monroe Township (now in Wyoming County).

The Harveys Lake and Towanda Branch of the Lehigh Valley Railroad was built during the late 1800s. It ran directly from Wilkes-Barre to Harveys Lake.

During the 1890s, railroad lines were established from the lake to the communities of Pittston and Towanda. Harveys Lake became a major tourist destination in the township. Warden Place and Sandy Beach became popular recreational areas near the lake in the early 1900s.

Within this same time period, there were three hotels, two hundred cottages, sixty boathouses, and four steamboats on Harveys Lake. The steamers were used for carrying passengers and freight. Recreational steamboat rides on the lake were commonplace between 1900 and 1920. In 1968, Lake Township lost its major tourist attraction — Harveys Lake. The region around the lake broke away from the township and was incorporated as a borough.

Today, the township is made up of thick forests and farmland.

According to the United States Census Bureau, the township has a total area of 26.7 square miles (69.1 km), of which 26.7 square miles (69.1 km) is land and 0.07% is water. Pikes Creek is a village in Lake Township. PA 29 runs north to south through the center of the municipality. PA 118 travels east to west through the southernmost portion of the township. The northwestern portion is made up of mountains and thick forests. The eastern and southern sections of the township are made up of hills, forests, and farms.
