Lake Elmo is a city in Washington County, Minnesota, United States. The population was 8,069 at the 2010 census.

Much of the area within the city limits is still farmland, giving the city a rural appearance. Following the loss of a lawsuit against the Metropolitan Council, a regional planning authority, the Minnesota Supreme Court in 2005 ordered that Lake Elmo had to compile a plan in accordance with the Councils regional development guide. The population of Lake Elmo is developing rapidly. It is projected that by 2040, the population of the city will be over 21,000.


The city took its name from nearby Lake Elmo. Lake Elmo began with one farm in 1852 on the southwest corner of the intersection of what is now Manning Avenue and 30th Street, just southeast of downtown Lake Elmo and across the highway from the Lake Elmo Airport (FAA LID: 21D). The barn was originally built in 1875 and restored in 1998 as a house. The 1852 farmhouse was intentionally burned down in March 2007.


According to the United States Census Bureau, the city has a total area of 24.36 square miles (63.09 km2); 22.25 square miles (57.63 km2) is land and 2.11 square miles (5.46 km2) is water.

Minnesota State Highway 36 runs east–west along Lake Elmo's northern boundary line. Interstate 94 runs east–west along Lake Elmo's southern boundary line. Minnesota State Highway 5 serves as a main route, also running east–west.
