Jacob "Jaap" Eisse Bulder (27 September 1896 – 30 April 1979) was a Dutch footballer who played as a forward.

[1] Bulder played as a centre-forward for hometown club Be Quick, having made his debut on 23 October 1910 against WVV at the age of 14.

He was considered the greatest footballer from the Northern Netherlands during his playing career; he was a great dribbler, a prolific goal scorer, and a technician who had practiced his technique with a tennis ball with his brother Evert Jan during their early years.

His critique cost Bulder his debut in the national team, although he was still part of the 1920 Summer Olympics in Antwerp.

He only returned to the national team after twenty months, when he would play in the inside forward trio with his club teammates Appie Groen and Harry Rodermond.
