Anchor Hocking Company is a manufacturer of glassware. 
The Hocking Glass Company was founded in 1905 by Isaac Jacob (Ike) Collins in Lancaster, Ohio, and named after the Hocking River.
That company merged with the Anchor Cap and Closure Corporation in 1937.

From 1937 to 1983, the company operated the oldest glass-manufacturing facility in the United States, established in 1863, in Salem, New Jersey.
Anchor Hocking's wine and spirit bottles were crafted at a factory in Monaca, Pennsylvania.
It also had facilities in Elmira, New York, and Streator, Illinois.

The company was the sponsor of the radio drama Casey, Crime Photographer. 
It was also slated to sponsor television's first late-night talk show, The Don Hornsby Show, before Hornsby suddenly died shortly before its debut.

Anchor Hocking and their headquarters in Lancaster, Ohio, are a focus of Brian Alexander's February 2017 book Glass House.
