Per Michael "Joe" Ljunggren (22 March 1962 – 17 July 1995) was a Swedish outlaw biker, gangster and member of the Bandidos Motorcycle Club. Ljunggren was a central figure in the Nordic Biker War, in which the Bandidos feuded with the Hells Angels. He was shot dead while riding his motorcycle on the E4 motorway in Småland. The murder remains unsolved, but police believe members of the Hells Angels to be responsible.
