Merlynston is a residential locality in Coburg North, 11 km north of central Melbourne.
In 1919 Donald Bain bought the 31 hectares Station Heights estate, immediately west of the Coburg North railway station. He subdivided it into housing blocks and renamed it after his daughter Merlyn. He became a local councillor and president of the Merlynston Progress Association which had a hall in Novian Street. The railway station was renamed Merlynston and the street to its immediate east is Bain Avenue.
