Pennsylvania Route 343 (designated by the Pennsylvania Department of Transportation as SR 0343) is an 8.21-mile (13.21 km) route between Lebanon, Pennsylvania and Fredericksburg, Pennsylvania. It begins at PA 72 and ends at Exit 6 of Interstate 78. State Route 343 heads mostly through urbanized areas, with several rural areas also surrounding. There is a concurrency with U.S. Route 22 near the northern terminus.

State Route 343 has had a number of different realignments, most of them relating to the northern terminus of the highway. The highway originally terminated at an intersection with SR 443 in Lickdale, moved to end in the community of Bordnersville soon after. The highway was then extended along the local continuation to end at U.S. Route 22 at an intersection in Harpers Tavern. In 1963, State Route 343 was moved back to Lickdale, and seven years after, moved to its northern terminus, thirteen years after the construction of Interstate 78.
