Johannes "John" Jacobus Bosman (born 1 February 1965) is a retired Dutch footballer who played as a striker.

A prolific goalscorer for both club and country, he played professionally for 19 years, most notably with Ajax (five seasons) and Anderlecht (five), surpassing the 100-goal mark with both clubs and winning a total of eight major titles combined.

Nicknamed Bossie, Bosman represented Netherlands at the 1994 World Cup and Euro 1988, helping the national team win the latter tournament.

Born in Bovenkerk, Amstelveen, Bosman began his professional career at AFC Ajax, making his Eredivisie debut on 20 November 1983 at the age of 18, in a 5–2 home win against Roda JC, scoring in the match. He finished his first season with four goals in 14 games.

From 1984–87, Bosman and fellow youth graduate Marco van Basten scored an astonishing 138 league goals combined (48 for Bosman), as the Amsterdam outfit won the 1985 national championship and two cups. After van Basten left for A.C. Milan in the 1987 summer, he netted 25 goals in 32 games, with the club finishing second to PSV Eindhoven; he also helped his team to the season's UEFA Cup Winners' Cup final, a 0–1 loss against KV Mechelen - the previous year, as Ajax won the competition, he was crowned top scorer with eight goals.
