Le Sauk Township is a civil township in Stearns County, Minnesota, United States, located immediately north of the city of St. Cloud and encompassing 10.6 square miles (27.5 km²) along the Sauk and Watab Rivers.

Settled beginning in 1854 by pioneers drawn to the fertile river valleys for farming and milling, the township was officially organized in 1860, reflecting the rapid European American expansion in central Minnesota following the 1851 treaties that ceded Dakota and Ojibwe lands. Early infrastructure focused on river-based industries, including quarries of crystalline syenite and gristmills like the one established by the Sartell family in the 1860s, which supported local agriculture and stone extraction.

As of 2023, Le Sauk Township has a population of 1,482 residents, with a median age of 45.4 years and a population density of about 145 people per square mile, characteristic of its rural, low-density landscape dominated by farmland and scattered housing.[3] The economy centers on agriculture and related activities, bolstered by a median household income of $99,792—higher than both Stearns County and state averages—along with significant homeownership (95%) and short average commutes of 21.2 minutes to work in nearby St. Cloud.

The township's development intertwined with broader Stearns County events, including Civil War enlistments from its residents in the 1860s and ongoing investments in bridges and roads over the Sauk River to connect it to regional trade routes. Today, it remains a quiet residential and agricultural community, with 73% of households comprising married couples and a low poverty rate of 5.8%, underscoring its stable, family-oriented character.
