Kari Juhani Valdemar Peitsamo (born 26 August 1957) is a Finnish musician whose style has changed over the years from acoustic avant-garde pop to electric rock.

Kari Peitsamo started his career with the EP Kari Peitsamo ja Ankkuli, which was created with the assistance of Juuso Nordlund and Kaj Martin, the backing group of Juice Leskinen, on the studio time left over from Leskinen.

Later on, Peitsamo's acoustic guitar was switched to an electric one, and he was joined by the band Ankkuli, with its other members Harri Siirtola (bass) and Yrjö Majamaa (drums).

Another ensemble of his, Kari Peitsamo & Hirttämättömät, also released one album in 1998, called Bubblegum Warriors In Faded Jeans.

In 2019 his politics took a rightward turn resulting in him being uninvited from Ämy [fi] music festival for comments he made about multiculturalism and the Christchurch mosque shootings.
