Marananga is a settlement in South Australia. It was known as Gnadenfrei before 1918 when names of "enemy origin" were changed to sound less German.
The Gnadenfrei Lutheran Church was established, then a German school was established in 1879. The school's name was changed to Marananga in 1918, which is now also the name of the locality. Gnadenfrei means 'grace' and 'freedom'. Marananga means "My hands" in the Aboriginal language of the Overland Corner tribe.
