The Kaatz Icehouse was a historic ice cutting facility located on the shore of Kaatz Pond, off Whitney Road in Trumbull, Connecticut. Built in 1908, it served in this role until 1955, and was believed to be one of the last surviving structures of this type in the state. It was listed on the National Register of Historic Places in 1977. Following its demolition in 1978, it was delisted in 2009.
It was a wood-framed structure, built in 1908 by Ernest Kaatz, who ran an ice harvesting operation between 1908 and 1955. The building was added to the National Register of Historic Places on September 19, 1977. It was razed in 1978 due to deterioration. The local historical society claims it was the last icehouse standing in New England.
