Tenax was a model name used by the German company Goerz at the beginning of the XXth century.

After Goerz was absorbed in the Zeiss Ikon company, the name Tenax was re-used successively for three different camera models:

• the Tenax II (Zeiss Ikon 580/27, 1938-1941)
• the Tenax I (Zeiss Ikon 570/27, 1939-1959)
• the Tenax Automatic (Zeiss Ikon 1960- )
• the Taro Tenax (Goerz 1912)
• the Plate Tenax (Goerz 1909)
• the Rollfilm Tenax (Goerz 1921)
• the Stereotenax (Goerz)
• the Manufok-Tenax (Goerz 1911)
• the Pocket Tenax (Goerz)
