The EOS-1 is a 35mm single lens reflex (SLR) camera body produced by Canon. It was announced by Canon in 1989, and was the professional model in the range. The camera also had a successor, the Canon EOS-1N, in 1994.

The original EOS-1 was launched in 1989.

On a physical level the EOS-1 resembled the T90, which had been designed for Canon by Luigi Colani. The EOS-1 had a single centrally-mounted autofocus point, plus basic weather sealing.
