Halfmoon Township is a rural area that has long been a major source of agricultural products. This rural atmosphere, with its low population density and proximity to the cultural attractions of Penn State University, has become appealing to people who have historically dwelled in or near a city; consequently, over the past twenty years, the population has increased dramatically, while the farming population has decreased. Still, Halfmoon Township has maintained its rural feeling, with all the associated pros and cons that come with country living.

Halfmoon Township was incorporated in 1847 and was the home to 2,357 residents in the 2000 census.

Halfmoon Township got its name from crude representations of half moons found carved on the trees marking the course of an Indian trail that passed through the valley.

Halfmoon Township is governed in accordance with the Commonwealth of Pennsylvania Code of Laws for a Second Class Township.
