Named after Saint Rochus, patron of the nearby Rochuskirche.
Rochus of Montpellier is a saint invoked against the plague. The church on Landstraßer Hauptstraße, begun in 1642, was dedicated to Saint Sebastian; in 1679 a plague brotherhood under the protection of Saint Rochus was founded there, and since then the church has borne both names. The Rochusgasse was named after the saint and his church in 1862.
