Mike Johnson (born 1952) is an American experimental rock guitarist and composer, best known as the co-founder and member of the Denver-based avant-rock group Thinking Plague.

He has also been a member of Hamster Theatre and The Science Group, and has collaborated with several musicians, including Bob Drake, Susanne Lewis and Janet Feder.

While at college in 1978 Johnson answered an advertisement at a local music store requesting a guitar player "into Henry Cow, Yes…"[1] This put him in touch with bass guitarist and drummer Bob Drake.

"Our goal was to combine the harder edge of progressive rock, as in Crimson and Yes, with the more modern tonalities and experimental approach as reflected in the work of the Art Bears, our major heroes at the time.

He toured with the 5uu's and Hail in the mid-1990s and has collaborated with a number of musicians, including Bob Drake, Susanne Lewis, Janet Feder and Fred Frith.
