Bert Willis Karlsson (born 21 June 1945) is a Swedish record company manager, entrepreneur, and former politician (Member of Parliament 1991–1994) and front figure of the New Democracy (Ny Demokrati) party.

As the owner and manager of the record company Mariann Grammofon AB, Karlsson became a familiar face to the Swedish public as the man behind singer Carola Häggkvist.

Attracting major media attention, and with a patriotic platform, the party received 6.7 percent of the vote in the parliamentary election in September.

When the New Democracy party imploded due to internal struggles and failed in the 1994 general election, Karlsson went back to being a full-time businessman.

[citation needed] In March 2005, Karlsson filled out an application for membership in the Liberal People's Party during a television interview.
