Strawberry Plains is an unincorporated community and census-designated place (CDP) in Jefferson, Knox, and Sevier counties in the State of Tennessee, United States. Before 2010, it was treated by the United States Census Bureau as a census county division. It is included in both the Knoxville Metropolitan Statistical Area and the Morristown Metropolitan Statistical Area.

The population of the CDP, which only covers the Jefferson County portion of the community, was 2,405 at the 2020 census.

The community that would become Strawberry Plains would be settled in 1785 by Adam Meek, a pioneer from North Carolina who would first settle in nearby Rocky Valley, and the first established settlement of newly founded Jefferson County. Meek would resettle near the banks of the Holston River in present-day Strawberry Plains following conflicts with inhabiting Native Americans.

Strawberry Plains is said to be named for the wild strawberries that grew there in abundance when white settlers from North Carolina first arrived in the area. William Williams, a North Carolina man, would acquire 1,200 acres in the community in 1808, and begin an agricultural industry on the wild strawberries grown in the land Williams had maintained. According to a history of the community written by local high school students circa 1935, the name Straw Plains was a shorthand name used by railroad porters and flagmen on trains that passed through Strawberry Plains, and that came to be used as the name of the local railroad depot and on some local post office postmarks.

Early in the Civil War, in 1861, the railroad bridge at Strawberry Plains was one target of Union sympathizers who aimed to burn several East Tennessee bridges to hinder Confederate military progress. The conspirators failed in their efforts to burn the Strawberry Plains bridge, but succeeded in their attacks of some of their other targets. In 1864, the bridge was destroyed in an artillery duel between Confederate and Union forces.

By the 1920s and 1930s, Strawberry Plains would emerge as an unincorporated town, with an established downtown area consisting several general stores, a gristmill, auto repair shops, several restaurants, gas stations, a bank, a train depot, and a post office. Immediate access to Knoxville, Dandridge, and Mascot courtesy of U.S. Route 11E (Andrew Johnson Highway), and the Southern Railroad would influence this growth of the community. By 1930, Strawberry Plains had a estimated population of nearly 500 residents.

By the 1970s into the 1990s, suburban sprawl would enter the community with the widening of US 11E and the increasing job market in the neighboring cities of Morristown, Sevierville, Jefferson City, and Knoxville.

With the completion of Interstate 40 in the southwestern part of the community in the late 1970s, the community would face confrontations, with the Knoxville City Council in the 1990s, with their controversial "finger" annexation of the commercial and retail corridors of exits 398 and 402 on I-40 on behalf of Knoxville mayor Victor Ashe's efforts to increase sales tax revenue in Knoxville.
