Leslie is a city in Ingham County in the U.S. state of Michigan. The population was 1,851 at the 2010 census. The city is surrounded by Leslie Township, but the two are administered autonomously.

Leslie was first settled by Elijah Woodworth in 1836, who built the first log cabin in the city. It was originally named Meekerville after a pioneer to the area, Benjamin Meeker. Jerry G. Cornell named the town after a prominent Leslie family in eastern New York, his home state. The name Leslie was adopted officially when a post office was assigned to the area in 1841. Leslie was later incorporated as a village in 1869, and as a city nearly 100 years later in 1968.

The Leslie Public School District is a small, rural district that educates nearly 1,400 students. The new Leslie High School was built in 1996 at 4141 Hull Road, and upgraded the old high school building into the middle school. The old middle school on Woodworth street (which was once a high school) was about 100 years old, and is now abandoned. The school district's mascot is the Leslie Blackhawk and the school colors are orange and black. Leslie's one public school has an average graduating class of between 100 and 130 students.

Also located in Leslie is White Pine Academy, a public school academy that is charted by Saginaw Valley State University White Pine Academy was founded in 1999 by a group of local parents looking for a back-to-basics curriculum and small class sizes. In 2005, White Pine Academy built a new facility at 510 Russell Street.

In 2008 the Leslie Blackhawks football team played for the Division VI state championship at Ford Field, but fell short to the Montague Wildcats, 41–20.

Distance running has been prominent in Leslie. An annual road race is held in mid-August during the annual Blackhawk Festival at the high school. It runs through the outskirts of the city and finishes on the track. Leslie High School's men's cross country running teams have won 14 consecutive conference championships (1990–2003) and one Class C state championship (1993).
