Martinus Bosselaar (January 16, 1936 – June 6, 2018) was a Dutch footballer who played as a left winger.

Bosselaar and Sparta both agreed on a return to the club as his heart was still at the other side of the city and his contract had a clause saying that he could leave the club to rejoin Sparta at any time.

Eventually Feyenoord lost the case and Bosselaar left the club and returned to his love in football.

[1] Bosselaar played his first international match on October 16, 1955, in a 2–2 draw versus Belgium.

In his second cap against Norway he netted two of his in total four international goals in a 3–0 win.
