Northern Transylvania Holocaust Memorial Museum, Holocaust Memorial Museum in Șimleu Silvaniei, Romania.

The Northern Transylvania Holocaust Memorial Museum occupies the old synagogue of Șimleu Silvaniei at Strada 1 Mai nr. 6, built in 1876 in Romanesque Revival style. Restored in 2004 with a replaced roof and structural consolidation, it opened as a museum on 11 September 2005. Its displays document the Jewish community of the town and nearby villages such as Giurtelecu Șimleului and Nușfalău.

The synagogue functioned for the Jewish community until 1944, when residents were forcibly moved to the Cehei ghetto and subsequently deported to Auschwitz-Birkenau. The building remained abandoned for decades before being restored in the early 2000s to serve as a memorial.

The synagogue served Jewish families from Șimleu Silvaniei and nearby villages such as Giurtelecu Șimleului and Nușfalău. Since 2005 it has housed the Northern Transylvania Holocaust Memorial Museum, run by the Jewish Architectural Heritage Foundation of New York and the Hebraica Memorial Association of Nușfalău. Student guides, an initiative begun by high-school student Natalia Gross, lead tours for school groups.

The museum is at Str. 1 Mai nr. 6 in Șimleu Silvaniei. Student guides offer daily tours tailored to school groups, and the Șimleu Silvaniei Multicultural Holocaust Education and Research Center hosts lectures and seminars for students, teachers and academics. The building is listed as historic monument SJ-II-m-B-05125.

The museum's guided tours are led by local students, a programme started by Natalia Gross while she was still in high school. In 2006 the museum hosted Romania's first Holocaust Memorial Olympiad, organised with the Ministry of Education, and in spring 2008 it opened the Șimleu Silvaniei Multicultural Holocaust Education and Research Center for lectures and seminars.
