Logenhaus, Cultural heritage monument in Lübeck, Germany.

The Logenhaus is a brick building with classical design elements located in Lübeck's Old City. It features symmetrical windows and carefully crafted facade details that make it a characteristic example of Hanseatic architecture.

The site belonged in the Middle Ages to a row of courtyards on the former Ritterstraße; the first known owner was cathedral dean Johannes de Campen in 1340, and August Hermann Francke was born in the house standing here in 1663. In 1862 the lodge Zum Füllhorn, founded in 1772, bought the largely built-over plot and erected the present lodge house in 1882, extended in 1926. After the Nazis banned the lodges, it was sold under duress on 19 July 1935; the city archive moved in and installed a six-storey steel stack, and the building survived the air raid of 29 March 1942. Returned legally in 1950, it was vacated only in 1961 and reconsecrated as a lodge house in 1962.

The house has belonged to Lübeck's oldest lodge, Zum Füllhorn, founded in 1772, since 1862. Today it serves all the city's lodges, including Zur Weltkugel and the 1950-founded Zur Weltbruderkette, plus the women's Rebekka-Loge zur Lübschen Hanse and the mixed Esther Chapter No. 21. From 1949 to 2023 the Jürgen-Wullenweber-Loge of the Odd Fellows rented space here.

The Logenhaus stands at the corner of Schildstraße 22–30 and St.-Annen-Straße 2, a few steps from the Aegidienkirche in Lübeck's Old City. The building can be rented for events and celebrations, but it is not a public museum; visits depend on the lodges that use it. The 1942 air raid left the house standing.

The 1926 coloured glass windows with Masonic motifs were destroyed after the Nazis forced the sale of the house on 19 July 1935; the lodge recovered it legally in 1950 but only moved back in 1962, after the city archive left for its new building at the Dom.
