Saint Nicholas church in Grójec, Gothic church in Grójec, Poland.

Saint Nicholas Church in Grójec is a single-nave, oriented Gothic church built of brick in the Polish bond, with fieldstone in the foundation. The chancel was finished in 1398 and the whole church in 1480; it was enlarged in 1520–1530. The neo-Gothic west facade dates from 1833, and the side chapels are plastered. A sundial dated 1621 with a Latin inscription is on the south wall.

Founded probably by Duke Janusz I the Elder of Mazovia, the church's chancel was finished in 1398 and the whole building in 1480. It was enlarged around 1520–1530, and the side chapel of Saint Anne was added in 1599 through the efforts of parish priest Wawrzyniec Pindovius. Plundered and burned during the Swedish Deluge, it was rebuilt by 1746; in 1828, 1833 and 1868 renovations under priest Kazimierz Celiński removed the western towers. Damaged in the first days of World War II, it was rebuilt as early as December 1939.

Local tradition holds that soldiers sharpened their swords on the 1482 sandstone baptismal font, which bears the mason's mark and the Półkozic coat of arms of the founder. Piotr Skarga was baptised at this font, and a 1855 inscription plaque in the church commemorates him, funded by the Grójec hospital foundation.
