Named after Margaretengürtel, the section of the ring road named after the Margareten district.
This stretch of the Gürtel (the ring road) was named in 1881 after the suburb of Margareten. Margareten takes its name from a chapel to Saint Margaret of Antioch, founded in 1388–1395 in the local manor house – not, as older books claim, from Margarete Maultasch. The station was first spelt ‘Margarethengürtel’; the ‘h’ went after the 1901 spelling conference.
