Datuk Arumugam Rengasamy (also known as Spiderman) was a legendary Malaysian international football player from Selangor.

[3] R. Arumugam was called up to the Malaysian national football team in 1973 for the World Cup qualifying round matches in Seoul, South Korea.

In recognition of his services to both state and nation, the Football Association of Selangor and Public Bank, where Arumugam had been employed, started a trust fund in his name on 5 January 1989.

On 4 June 2011, Yang Dipertuan Agong posthumously awarded him the Panglima Jasa Negara (PJN), which carries the title "Datuk".

The character of Muthu Kumar in Ola Bola, a 2016 film chronicling the Malaysian national team's road to the 1980 Olympic qualifiers, was based on Arumugam.
