Sankt-Gertrauden-Kirche, Protestant church in Buckau, Magdeburg, Germany

Sankt-Gertrauden-Kirche is an evangelical church in Magdeburg's Buckau district, built of rubble stone masonry with sandstone details and mixing Gothic and Romanesque elements. Its five-bay nave has a pitched roof, a four- to five-storey west tower with a pointed spire, three west portals and a low semi-circular apse; a south annex with its own entrance holds a second small apse.

A chapel dedicated to Saint Gertrude is documented in Buckau in 1061; the saint was patron of the weavers who settled there. The church was destroyed in the Schmalkaldic War and rebuilt in 1592, then destroyed again in 1631 during the siege of Magdeburg. Abbot Crucius rebuilt it in 1636; the present church was begun in 1867 to plans by royal master builder Sieger and consecrated in October 1869.

The church is dedicated to Saint Gertrude of Nivelles, patron saint of weavers, many of whom lived in Buckau. The apse and east gable windows were donated by the widow Wagenführ, her daughter and her son-in-law, the banker Ziegler, and made in a Berlin workshop. Since 2003 the Förderverein St. Gertraudenkirche Magdeburg Buckau e. V. has supported the building.

The church is located at Schönebecker Straße 117 and remains open to visitors throughout the year. Regular Protestant services are held here, and the grounds include a cemetery with historical gravestones to explore.

A lapidarium was established on the church grounds in 2011, collecting historical gravestones and monumental pieces from the region. This collection preserves traces of Magdeburg's past in one accessible location.
