Pennsylvania Route 287 is a 63.9 mi long state highway in the Tioga Valley of Pennsylvania. Route 287 begins at an intersection with U.S. Route 220 in the community of Larrys Creek in Piatt Township, Lycoming County to an intersection with Pennsylvania Route 49 just south of the New York state line in Lawrenceville, Tioga County. The route follows Larrys Creek through several isolated communities, including Salladasburg and English Center, before working its way towards Hoytville, where it meets Pennsylvania Route 414. The route ends up in Wellsboro, where it meets U.S. Route 6, and reaches Tioga.

The alignment of Route 287 has been successor to a set of plank roads from Larrys Creek to Lawrenceville. The southern plank road, known as the Larrys Creek Plank Road, dates back to 1850 as short highway from Larrys Creek to Salladasburg, and was completely gone by 1900. The second part followed the Tioga and Lawrenceville Plank Road, which although is named from Tioga to Lawrenceville, went from Wellsboro to Tioga. The portion to Lawrenceville was never constructed. The route also followed several postal routes in the area. In 1911, the Sproul Road Bill was passed, and Route 287 became segments of Legislative Route 22, Legislative Route 106, and Legislative Route 353. In 1924, the northernmost portion was designated Route 4 and the Susquehanna Trail. This was changed to part of U.S. Route 220 in 1926.

In 1928, U.S. Route 111 was designated, and along with Pennsylvania Route 84, consisted of the alignment of Route 287. Route 111 was redesignated as part of U.S. Route 15. The highway was redesignated as Route 287 in 1961 when Route 84 was decommissioned in favor of Interstate 84. The route was extended from Tioga to Lawrenceville in 2008, when the construction of U.S. Route 15 was finished to the New York state line, and Route 287 was extended to Route 49.
