Heath Township is a township in Jefferson County, Pennsylvania, United States. The population was 117 at the 2020 census, down from the figure of 124 tabulated in 2010. It was named for early Jefferson County settler Elijah Heath. Heath Township is the second-smallest municipality in Jefferson County.

Heath Township is a popular tourist destination for avid sportsmen, with many seasonal private residences maintained by out-of-town residents, as well as a wide variety of campgrounds ranging from rustic accommodations to modern-day amenities. The Farmers Inn is a restaurant specializing in American cuisine and also maintains a petting zoo, three mini golf ranges, a candy shop and ice cream parlor, bakery, furniture and gift shops.

The municipality is the home of Clear Creek State Park, which is operated and maintained by the Pennsylvania Department of Conservation and Natural Resources.

From 1912 to 2017, it was also the home of Heath Pump Station, a compressed natural gas producer owned by New York-based National Fuel Gas. The pump station also shared property with a dam that allowed Callen Run to flow into the Clarion River. The dam provided water to the engines running the station as well as a trout fishing hatchery built in 1955 and operated and maintained by the Heath Township Sportsmen's Association. Despite a persistent natural gas odor and pump noise, anglers were undeterred from fishing that portion of Callen Run.

Heath Pump Station stopped compressing gas in 2007, with its building being torn down a decade later. Of historical note, the pump station supplied much of northcentral Pennsylvania and western New York with natural gas using a compressor pump manufactured by Snow Steam Pump Works in Buffalo, New York. The pump weighed 98 tons and had a length of 50 feet, with its 13-foot flywheel alone weighing 11 tons. Though state of the art for its time, its use was supplanted by more modern technology capable of producing more gas more efficiently, and a smaller plant was constructed in the vicinity to replace the Heath Station. That plant is known as the Eldred Compressor Station. Relics from the Heath Station were later donated to the Jefferson County Historical Society and one of the Snow engines was donated to the Western New York Gas & Steam Engine Association.

The fish hatchery remains, and the sportsmen's association keeps a supply of approved food to allow young children visiting the hatchery an opportunity to feed the fish. The dam is slated to be eventually removed from the property to allow native trout to swim from the Clarion River back up to Callen Run in warmer weather.

Heath Township is in northern Jefferson County, bordered to the north by Elk County. The Clarion River, a west-flowing tributary of the Allegheny River, forms the northern border of the township and the county line. The township includes the unincorporated community of Dutch Hill.

According to the United States Census Bureau, the township has a total area of 29.2 square miles (75.7 km), of which 28.8 square miles (74.7 km) are land and 0.35 square miles (0.9 km), or 1.25%, are water.
