Pennsylvania Route 283 (PA 283), officially State Route 0300 or SR 0300 due to the presence of Interstate 283 (I-283), is a 29-mile-long (47 km) state highway in the U.S. state of Pennsylvania. A freeway for nearly its entire length, it connects Harrisburg to Lancaster, paralleling the old U.S. Route 230 (US 230, now partly PA 230). The route follows a generally northwest-southeast direction and is signed east-west. The number was assigned based on the function the route serves as a southeastern extension of I-283, but I-283 and PA 283 are not the same roadway; the two intersect at a partial cloverleaf interchange.
