Mikael Christian Wiehe (born 10 April 1946 in Stockholm) is a Swedish singer, multi-instrumentalist and composer.

As the main songwriter and driving force of Hoola Bandoola Band he was also one of the most important people in the progg movement.

He is a leftist folk musician, dealing with what he considers right and wrong in the society from the eyes of the proletariat, but he also writes personal, non-political songs.

Wiehe has also translated many of Bob Dylan's songs into Swedish, some of which were performed by Totta Näslund.

A number of high-profile Swedish artists, including Joakim Thåström, Lars Winnerbäck, Dregen, Lisa Ekdahl, Timbuktu, Stefan Sundström, Idde Shultz and Anna Stadling (of Hovet), Ebba Forsberg, Thomas Wiehe and Peter Clemmendson, performed Wiehe's songs in front of approximately 20,000 people.
