Elizabeth Township lies between the shores of the Youghiogheny and Monongahela Rivers with a population of roughly thirteen thousand people, encompassing nearly twenty-three square miles in the southeastern section of Allegheny County. Elizabeth Township was formed from a part of Rostraver Township and was originally part of three counties: Bedford, Westmoreland, and Allegheny. This area was included in the large tract of land that was granted to the Penn family by King Charles II in 1681.

​

In 1788, Allegheny County was formed and Elizabeth Township, named in honor of Elizabeth Bayard, wife to the founder of Elizabeth Village, was incorporated as one of its original seven townships. Some villages located in Elizabeth Township are Boston, Greenock, Buena Vista, Industry, Blythedale, Blaine Hill, Mt. Vernon, Victory, and Central.
