Hans Olof "Putte" Wickman (10 September 1924 – 14 February 2006) was a Swedish jazz clarinetist.

Born Hans Olof Wickman in Falun, he grew up in Borlänge, Sweden, where his parents hoped he would become a lawyer. He nagged them to allow him to go to high school in Stockholm. When he arrived in the capital he still did not know what jazz was, and said in an interview many years later he was probably the only 15-year-old who did not. Since he did not have access to a piano in Stockholm, he was given a clarinet by his mother as a Christmas present – a life-changing event, as it turned out, as by then he had started to hang out with "the worst elements in the class – those with jazz records".

Artie Shaw and Benny Goodman were the role models for the young Wickman, who, already in 1944, had turned to music full-time. He was taken on as band leader at Stockholm's Nalen and in 1945 the newly founded Swedish newspaper Expressen described him as the country's foremost clarinet player. Wickman considered himself self-taught; he never took classes on the instrument.

He led a band at Nalen for eleven years, and during the 1960s he ran the big band at Gröna Lund and at Puttes, the club he co-owned, at Hornstull in Stockholm. In interviews in his later years, it was clear that he rated his church performances very highly. He was until shortly before his death still active as a musician, giving concerts every year. The technique and tone was still of the highest class, as was the well-pressed suit with a white handkerchief in the breast pocket.

In 1994, Wickman received the Illis Quorum gold medal, today the highest award that can be conferred upon a private Swedish citizen by the government of Sweden.[2] Wickman was a member of the Royal Swedish Academy of Music.
