Congers, named after Abraham B. Conger, was settled in the late 1600s by Dutch, German and English settlers and was known as Cedar Grove Corner and then Waldberg, which in German means "forest mountain".

In the 1800s the Congers railroad station, three churches, a school, the firehouse and the Central, and Globe hotels were built. The first floor of the then Globe hotel on the southeastern corner of Congers Road is presently the Last Chance Saloon. The Clarktown Dutch Reformed Church still stands at the corner of Congers Road and Kings Highway.

Kings Highway was the first major road in the county and for many years the only road from New York to Albany.

Today there exist nine structures with recognized historical markers dating back to the 1700s, including the DeBaum House on Kings Highway, the Smith House on Gilchrest Road and the Snedeker House, where the Commander-in-chief George Washington is believed to have spent a night.

St Paul's Church on Lake Road built in the early 1890's was Clarkstowns' first Catholic Church.

Congers has two elementary schools, Congers Elementary and Lakewood Elementary. Students from these schools will attend Felix Festa Middle School and then Clarkstown North High School. Congers is also the home of Rockland Country Day School, which accepts students in grades PreK-12 and was founded in 1959.
