Kolmoskanava (also known as TV3 and informally as Kolmonen) was a Finnish television station owned and operated by Oy Kolmostelevisio Ab, a joint venture between MTV Oy, Yle and Nokia. The channel was launched on December 1, 1986, and closed on December 31, 1992, replaced by MTV3.

The channel was the first nationwide commercial channel in Finland, although it did not produce any of its programmes themselves, instead relying on imported programmes (mostly from America), sports and a small number of Finnish programmes, most notably the bingo game show Megavisa, which aired from 1991 until 1992 on Kolmoskanava, and from 1993 until 1995 on its successor channel MTV3.
