Breinigsville is an unincorporated community and census-designated place (CDP) in Lehigh County, Pennsylvania.

Breinigsville was named for George Ludwig Breinig (January 31, 1733 – May 12, 1812), a German immigrant who came to the United States on board the ship Lydia, arriving in Philadelphia on October 13, 1749.

He originally settled in Weisenberg Township (tax records show he was assessed 9 pounds in 1762).

On May 10, 1771, Breinig purchased around 100 acres (40 ha) of land and a stone dwelling for 700 pounds from Peter and Catherine Trexler of Trexlertown.

Among his seven children was Peter Breinig, his youngest son who founded Breinigsville and owned a 123-acre (50 ha) farm.

In the 1860s, the Catasauqua and Fogelsville Railroad used the grade to build from Trexlertown, on its main line, into Breinigsville, as part of a branch to serve local limonite (iron ore) mines.

On the western edge of Breinigsville, a United Brethren Church was built in 1880 whose membership at one time peaked at around 40.

[3] The village had a lumber, grain, and coal depot, a carriage works, and a general store, which are no longer in existence.

Breinigsville lies within the hot-summer humid continental climate zone (Köppen: Dfa), and experiences four distinct seasons.

Winters are cold and snowy with few sunny days, and with a January daytime average high of 34 °F (1.1 °C).

Toward the late 1970s and 80s due to relatively cheaper land prices and close proximity to New York, a number of major distributors and warehouses have relocated to the area.
