Radin Mas is a neighbourhood within Telok Blangah Estate, located in Bukit Merah, Singapore.

Kampong Radin Mas was a small Malay village situated on the foothills of Mount Faber in Telok Blangah.

After her mother died in a fire which was planned by some enemies intended to kill both her and her daughter, she fled from Java for Singapore together with her father, the crown prince, to avoid persecution at the hands of her uncle, the sultan.

Radin Mas came to be of prominence during 2007's National Day Rally when Prime Minister Lee Hsien Loong called it as the model of Singapore by 2020 when the proportion of Singaporeans above 65 years of age is expected to be 1 in 6.

Today, while no street bears the name, the area is frequently referred to as Radin Mas.
