Iosefin Synagogue, Orthodox synagogue in Iosefin district, Timișoara, Romania.

The Iosefin Synagogue in Timișoara is an Orthodox house of worship featuring four domes and narrow horseshoe-shaped window openings on its exterior. The structure at 55 Iuliu Maniu Street displays Moorish-influenced brickwork with decorative dentil detailing.

The Orthodox community of Iosefin formed in 1871 and met in rented rooms until the synagogue, designed by Karl Hart, was inaugurated on 18 September 1895, on the eve of Rosh HaShanah, with Mayor Carol Telbisz present. Rabbi Bernát Schück led the building effort. The synagogue was enlarged in 1910; photographs from 1914–1915 show one central dome, while the present two central and two smaller lateral domes came later.

The interior displays geometric patterns on the walls and four cast-iron pillars that support the ceiling arches. The wooden Aron HaKodesh holds the Torah scrolls at the heart of the prayer space.

The synagogue is at 55 Iuliu Maniu Boulevard in the Iosefin district, on the city's south-western side. It holds services on Friday evenings, Saturday mornings and High Holidays, so visits at other times depend on the congregation. Ask the community in advance about entry to the prayer hall.

The complex once housed more than just a prayer room - it included a kindergarten, ritual bath, and kosher slaughterhouse in one coordinated space. These integrated facilities once formed the center of neighborhood Jewish community life.
