Nikon FG-20 is a 35mm film SLR camera, manufactured by Nippon Kogaku K. K., Tokyo, Japan, (Nikon Corporation since 1988), and produced between 1984-1986.

The Nikon FG-20 is the successor to the earlier Nikon EM and Nikon FG cameras. It is actually a downgrade from its most direct predecessor, the FG. The FG-20 could be considered a variant of the FG, as the only differences between the two is the omission of program auto exposure mode and TTL (through the lens) flash metering.
