The church of Saint John the Baptist (or as written by the parish H. Joannes de Dooper or as a variant in Dutch Sint Johannes de Doper) is a Roman Catholic church in Pijnacker in the Netherlands.

When diocesan boundaries were redrawn it became part of the Roman Catholic Diocese of Rotterdam.

The parish website officially shows it as "H. Joannes de Dooper," (with no "h" and with two "o"s) but others list it as Heilige (or Sint) Johannes de Doper (with an "h" and with only one "o.")

Above the entrance door of the church is found a bas-relief showing the baptism of Jesus by John.

[1][2] The church is a registered national monument along with the attached presbytery.
