Wheatland is a former borough in Mercer County, Pennsylvania, United States, along the Shenango River. The population was 583 at the 2020 census. On January 1, 2024, Wheatland merged with the neighboring city of Hermitage after residents of both communities voted to approve the merger in November 2022.

Prior to the construction of the first iron furnace in the area, the land that would become Wheatland was primarily rural, and split between two family farms, the Shilling family, who arrived first, founded by pioneer George Shilling, and the Canon family, who arrived later in 1797 and where founded by Squire Canon, and joined by a Presbyterian Reverend James Satterfield. Additionally, Dr. John Mitcheltree, the pioneer physician of the entire Shenango valley during its early settling also resided in what would become Wheatland.

Wheatland would be platted in 1865 and would be incorporated on February 12, 1872. Wheatland was designed as a company town for the Wheatland Iron Co. and the Wheatland Bessemer Steel Co. and would remain a manufacturing hub throughout much of its early history, diversifying with the opening of a Sawhill Manufacturing Co. lumbermill in 1940.

On November 10, 1908, South Sharon Borough attempted to annex a portion of Wheatland, from Kedron street in the south to Bond street in the north, and from Beechwood avenue in the east to Hamilton avenue in the west. However, the Court of Common Pleas of Mercer County overruled the attempt on May 7, 1912. On December 18, 1918, Wheatland borough annexed a 30.85 acre portion of Hickory Township via borough ordinance that was approved by the Court of Quarter Sessions of the Peace of Mercer County in January 1919. On June 7, 1952, Wheatland borough annexed another parcel from Hickory Township approved by the Court in September 1952, bringing the borough to its final borders prior to absorption.

Wheatland suffered catastrophic damage on May 31, 1985, when an F5 tornado struck the area. In Wheatland, over 100 buildings were leveled, and 18 fatalities are associated with this tornado, with most being in Niles, Ohio.

From 2002 to 2007 Wheatland attempted to form an independent School District, instead of being serviced by the Farrell Area School District. This effort would see serious backlash from local residents, many of whom had moved to Wheatland for the sole purpose of being serviced by the Farrell School District, and a lawsuit ensued to instead have Wheatland be serviced by the West Middlesex Area School District. The suit eventually reached the Commonwealth Court of Pennsylvania where Judges Renée Cohn Jubelirer, Doris Smith-Ribner, and James Gardner Colins struck down the secession, keeping Wheaton in the Farrell district, on account that the petition to do so, which reported 50.4% of taxpayers in favor, misrepresented what a "taxpayer" entailed in 2006.

From 1990 to 2009 Wheatland's mayor was Thomas R. Stanton who led efforts to preserve the borough's independence, personally negotiating for state resources to help residents and improve infrastructure with his governance dominating the politics of the borough in its final decades. During is departure Stanton campaigned in the borough council for support of his incoming replacement, Brian P. Estock, and ran for a single term on the borough council to help ease his transition.

In 2004 local politicians proposed the creation of Shenango Valley City, consisting of Wheatland, as well as Hermitage, Sharon, Farrell, and Sharpsville with the issue being put on the ballot in the form of a referendum. Then Governor of Pennsylvania, Ed Rendell voiced support for the measure and would be joined by Kathleen McGinty, Secretary of the Department of Environmental Protection, and Dennis Yablonsky, Secretary of the Department of Community and Economic Development with the trio touring the region to urge for voters to pass the motion. The city would largely be an expansion of Hermitage, whose city government would be retained including the office of mayor and its nine-member city council. The merger would have kept the various independent school districts intact. The effort would ultimately be defeated, and via the ordinance the issue of merger could not be brought up again until 2009.

In 2018 Wheatland formed a commission on the possibility of continuing its independence in a 137–73 vote. On November 8, 2022, a referendum was held over annexation into Hermitage which passed, stipulating automatic annexation on January 1, 2024. On top of the lack of feasibility to continue to financially support the borough, one of the leading causes for annexation was Hermitage's more pro-business outlook. Wheatland Borough Council would have its last ever meeting on December 12, 2023, lasting just 10 minutes, councilors and six-year mayor Ronald Viglio reflected on their service to their community, and where joined with officials from Hermitage thanking them for "friendship and kindness" in the annexation process. The borough was merged into Hermitage on January 1, 2024. The former borough council hall will be preserved as a museum on the history of Wheatland.
