The Metz Company was a pioneer brass era automobile maker established by Charles Herman Metz in Waltham, Massachusetts, from 1909 to 1922.

The Brass Era is an American term for the early period of automotive manufacturing, named for the prominent brass fittings used during this time for such features as lights and radiators. It is generally considered to encompass 1896 through 1915, a time when cars were often referred to as horseless carriages.
