Pennsylvania Route 44 (PA 44) is a 149.24 mi (240.18 km)-long state highway in the U.S. state of Pennsylvania. The route, which is signed north-south, is designated from Interstate 80 (I-80) and PA 42 in Buckhorn northwest to the New York state line near New York State Route 417 (NY 417) in Ceres Township.

Commissioned in 1927 by the Pennsylvania Department of Highways, PA 44 originally ran from the New York state line to Jersey Shore. Today, the highway is a scenic route from Columbia County to Potter County.

PA 44 begins in the census-designated place of Buckhorn in Hemlock Township, Columbia County, at an intersection with PA 42 and exit 232 of I-80. From here, the route heads northwest along two-lane undivided Buckhorn Road, passing businesses before running past homes in Buckhorn. The road continues through a mix of farmland and woodland with some homes through the Appalachians. PA 44 winds north and curves northwest to enter Madison Township, passing through more rural areas. The route runs through agricultural land with some woods and residences, turning west before heading back to the northwest, winding across a wooded ridge. PA 44 turns to the north and comes to an intersection with PA 642, at which point the two routes become concurrent along Danville Road. The road passes through farmland with some development and heads into the community of Jerseytown, where it passes homes and a few businesses and curves northwest to come to an intersection with PA 254. At this intersection, PA 642 ends and PA 44 continues northwest along White Hall Road, heading through agricultural areas with some woods and residences.

The route enters Anthony Township in Montour County, passing homes in the community of White Hall and running through agricultural and wooded areas in the Muncy Hills, turning to the west.

The road runs north-northwest through farmland with some development before it turns west and crosses the West Branch Susquehanna River onto Long Island, where it passes farm fields before heading over more of the river.

After crossing the river, PA 44 enters the borough of Jersey Shore and becomes Allegheny Street, immediately turning north onto North Main Street. The route runs between residences and businesses to the west and the West Branch Susquehanna River to the east, leaving Jersey Shore for Porter Township. The road passes more development to the west of the river, heading north-northeast to a trumpet interchange with the US 220 freeway on the border between Porter Township to the west and Piatt Township to the east. At this point, PA 44 forms a wrong-way concurrency with US 220 on a four-lane freeway officially signed as the "Frank D. Oreilly Highway", heading west into Porter Township. The freeway heads through wooded areas to the north of Jersey Shore, coming to a bridge over the Lycoming Valley Railroad. US 220/PA 44 reach a diamond interchange with Thomas Street that serves Jersey Shore before continuing southwest near residential development, passing under the Pine Creek Rail Trail before coming to a bridge over Pine Creek.

The route runs to the west of Mill Creek and heads north through wooded areas with some farm fields and residences. PA 44 heads into Sweden Township and continues through a mix of fields and woods with some homes and commercial development, crossing the creek. In the community of Sweden Valley, the route comes to an intersection with US 6. PA 44 is named Highway to the Stars from the border between Lycoming and Potter counties north to US 6 as it passes through Cherry Springs State Park, an International Dark Sky Park that is popular among astronomers and stargazers.

At this point, PA 44 turns west for a concurrency with US 6 on the Grand Army of the Republic Highway. The two routes head northwest through wooded areas with some fields and residential and commercial development to the north of Mill Creek, crossing into Eulalia Township. The road continues northwest and enters the borough of Coudersport as it passes to the south of UPMC Cole hospital.

From here, the road continues north for less than 100 yards (91 m) to a T-intersection with NY 417.

When PA 44 was commissioned in 1927, the route was designated from US 220 in Jersey Shore to the New York-Pennsylvania border. Northwest of Coudersport from PA 49 to PA 244, and from US 6 to US 220, the road was not paved. From Jersey Shore to Turbotville, PA 44 was assigned the PA 54 designation. From Turbotville to Jerseytown, the road was designated as PA 454. From Jerseytown to Buckhorn, PA 44 was numbered as PA 342. These designations were eliminated with an extension of PA 44 in 1941.

By 1940, PA 44 was extended east to Turbotville, replacing the previous PA 54 alignment. Also in the 1940s, PA 44 was completely paved from Coudersport to the New York state line. In the 1950s, PA 44 was largely extended to Mahanoy City in Schuylkill County.

By 1970, the road was truncated to its current southern terminus in Buckhorn.

On June 28, 2018, Governor Tom Wolf approved legislation that named the section of PA 44 in Potter County between the Lycoming County line and US 6 as Highway to the Stars, as it passes through Cherry Springs State Park. The idea for the name came from photographer Curt Weinhold, a Potter County resident. State Representative Martin Causer sponsored the legislation for naming the section of PA 44 as Highway to the Stars.
