Punxsutawney is a borough in southern Jefferson County, Pennsylvania, United States. As of the 2020 census, its population was 5,769. It is located approximately 84 miles (135 km) northeast of Pittsburgh. Punxsutawney is known for its annual Groundhog Day celebration held each February 2, during which thousands of attendees and media outlets visit the community for an annual weather "prediction" by the groundhog Punxsutawney Phil.

Groundhog Day is a tradition observed regionally in the United States and Canada on February 2 of every year. It derives from the Pennsylvania Dutch superstition that if a groundhog emerges from its burrow on this day and sees its shadow, it will retreat to its den and winter will go on for six more weeks; if it does not see its shadow, spring will arrive early. In 2025, the shadow was seen, auguring six more weeks of winter.
