C (sometimes written as C=) was a Finnish computer magazine targeted specifically at Commodore computers.

C was started in 1987 as a spin-off of MikroBITTI and was published roughly every two months. It was Finland's first ever computer magazine to only cover one specific family of computers. Originally, it covered the Commodore 64 (and to a lesser extent, its "bigger brother" Commodore 128) and the Amiga computers, but later it became more and more Amiga-centric, as the 64 and 128 were rapidly becoming obsolete.

Later, as the Amiga was also becoming obsolete and lost ground to the PC computers and games consoles, sales decreased rapidly, and C was discontinued in 1991.

Even today, with the exception of some minor console magazines, C remains the only Finnish computer magazine ever to specifically concentrate on one particular vendor.
