Pennsylvania Route 329 (PA 329) is a Pennsylvania state highway that runs for 12.9 miles (20.8 km) through Lehigh and Northampton counties in the Lehigh Valley region of the state. It runs from PA 873 in the North Whitehall Township village of Neffs east to PA 248 and PA 987 in Bath. The route is a two-lane undivided road that runs through a mix of rural and developed areas to the north of the cities of Allentown and Bethlehem, serving the communities of Balliettsville, Egypt, Cementon, and Northampton. PA 329 intersects PA 145 near Egypt and runs concurrent with PA 987 between East Allen Township and the eastern terminus in Bath.

PA 329 was originally designated in 1928 to run from Egypt south to U.S. Route 22 (US 22), US 309, PA 29, and PA 43 in Center City Allentown. The alignment between Cementon and Bath was designated as part of PA 145 in 1928. By 1940, the route was realigned to a new alignment in Whitehall Township.

In 1941, PA 145 and PA 329 switched alignments, with PA 329 heading east to PA 45 (now PA 248) and PA 987 in Bath and PA 145 heading south to US 22, US 309, and PA 29 in Allentown. PA 329 was extended west to US 309 (now PA 873) in Neffs and a branch of the route was designated between Balliettsville and US 309/PA 29 and US 309 Byp. at the northern edge of Allentown. The section of PA 329 between Balliettsville and Allentown was decommissioned by 1950.
