Pfarrkirche Neu-Erdberg, Parish church in Landstraße district, Vienna, Austria.

Pfarrkirche Neu-Erdberg is a Roman Catholic parish church at Hagenmüllergasse 33 in Erdberg, built 1954–1958 to plans by Robert Kramreiter as a reinforced concrete structure with concrete tracery windows. A tall glazed entrance facade faces the rectangular hall with lower side aisles; the choir ends in a flat conch, and a bell tower stands to the northeast. Inside, four pillars support a ceiling of convex concrete shells.

The Salesians Don Bosco built the Salesianum with a chapel dedicated to the Holy Guardian Angels between 1908 and 1910 to plans by architect Corradi. In 1939 the chapel was elevated to parish church and redesigned by Robert Kramreiter; war damage was repaired after 1945. The present reinforced-concrete church was built next to the Salesianum from 1954 to 1958, also to Kramreiter's plans, and the old chapel again serves as the house chapel.

The church is dedicated to Saint John Bosco, founder of the Salesians, whose Salesianum next door housed a chapel from 1908 to 1910. The main south portal carries an enamel mosaic by Otto Beckmann in eight panels showing the mystery of creation and the seven sacraments. The stained glass windows depict symbols of the church year and the descent of the Holy Spirit.

The church stands at Hagenmüllergasse 33 in Erdberg, with the entrance facade facing south and the bell tower to the northeast beside the choir. The tower, built as a hostel for Austrian school pupils during their Vienna week, is closed because of structural decay. The interior is supported by only four pillars, so two thirds of the altar area is visible from any seat.

The bell tower northeast of the church was built as a residential tower and served as a youth hostel, mainly for Austrian pupils from the federal provinces spending a week in Vienna (the "Wienwoche"). It is currently closed because it is structurally unsound.
