St. Cosmas und Damian, Roman Catholic parish church in Titz, North Rhine-Westphalia, Germany

St. Cosmas und Damian is a Roman Catholic parish church in Titz, North Rhine-Westphalia, built in red brick between 1889 and 1893 to designs by Erasmus Schüller and Hans Hubert Dreher. It is a three-aisled hall church with four bays, side aisles ending in 4/8 polygonal choirs, and a recessed three-storey bell tower to the west. The tower's square brick base carries a tall louvered pointed window, a round clock with light numerals, and a steep dark slate spire with a cross.

A church in Titz is documented by 1365, when a priest named Sibertus is recorded; the parish was independent by 1804. The 15th-century building was demolished in 1889 apart from its tower. The present church was built from 1889 to 1893 to plans by Erasmus Schüller, continued by Hans Hubert Dreher after Schüller's death in January 1890, and consecrated on 21 September 1893. In 1903 the old tower gained one storey.

The church is named after Saints Cosmas and Damian, two patrons associated with healing and craftsmanship. Visitors who enter the interior can still see signs of this devotion reflected in the window designs and altar furnishings.

The church stands in the centre of Titz, at the corner of the street leading to the market square, with the slender street lamp in front of the tower marking the entrance. The recessed door at the base of the tower is the way in; the parish office of the St. Irmundus/Titz parish can give details on opening times. The building is listed as number 30 in the municipality's monument list.

The oldest bell in the four-voice bronze peal was cast in 1578; it is a loan bell from the church of Neuwaldau in Lower Silesia, now in Poland. The high altar came from the previous church: a Flemish carved altarpiece made around 1520 and restored in 1858 and 1890.
