Church of Saint Andrew, Religious monument in Blatnice pod Svatým Antonínkem, Czech Republic.

The Church of Saint Andrew is a single-nave Baroque church with a semicircular presbytery, built in 1714–1717 on the site of an earlier Gothic church. Its facade has a pilaster frame and three round-arched windows; a prismatic tower with a clock and bell-shaped roof stands at the east end, with a cylindrical stair annex attached to its south side. The nave has a saddle roof and a barrel vault with lunettes.

The first church in Blatnice was built around the 11th or 12th century and first mentioned in 1346. After wars, fires and raids left it in ruins, it was demolished and replaced by a Baroque church built between 1714 and 1717, supposedly designed by Anton Ospela. Repaired after a fire in 1829, it was decorated with paintings by Joža Uprka in 1888 and restored in 2011.

The church is dedicated to Saint Andrew and serves as the parish church for the Roman Catholic parish of Blatnice pod Svatým Antonínkem. It is regularly included in the Noc kostelů (Night of Churches) event, when the building opens to visitors beyond regular services.

The church stands in the centre of Blatnice pod Svatým Antonínkem, in the Hodonín district of the South Moravian Region. The entrance is in the front facade beneath the tower, and a circular staircase is built into the cylindrical annex on the tower's south side. The church is regularly opened for the Noc kostelů (Night of Churches) event.

The tower is the only part of the earlier Gothic church that survived the demolition; the rest of the present building dates from 1714 to 1717. The architect is said to have been Anton Ospela. The tower was heightened at the end of the 1950s.
