John Achterberg (born 8 July 1971) is a Dutch former professional footballer who played as a goalkeeper for NAC Breda, FC Eindhoven and Tranmere Rovers.

However after refusing to sign a new contract he was dropped by John Aldridge for the 2000 Football League Cup final and replaced by Joe Murphy.

The game finished goalless, but was largely dominated by Millwall and John managed to save a penalty kick from Kevin Muscat, despite having to play through injury.

Achterberg's chances of re-establishing himself as Tranmere's first choice goalkeeper in 2006–07 were hampered by the signing and good form of veteran journeyman Gavin Ward.
