Rasipuram Subramaniyan Iyer Manohar (29 June 1925 – 10 January 2006) was an Indian actor who performed roles ranging from hero to villain to comedic characters.

But Manohar is best remembered for the negative roles he played, especially while facing off with M. G. Ramachandran in films such as Ayirathil Oruvan, Ulagam Suttrum Valliban, Pallandu Vazhga, Adimai Penn, Kaavalkaaran and Idayakkani.

Most of the 31 plays in which he acted - altogether totaling 7,950 performances - were adaptations or interpretations of historical incidents or mythological stories.

Famous among Manohar's plays are Ilangeswaran, Chanakkiya Sabadam, Soorapadman, Sisupalan, Indrajith, Sukrachariyar, Naragasooran and Thirunavukkarasar.

He was a pioneer in introducing 'dramascope' with stereophonic sound system, split second transformation of sets and pyrotechniques to represent battle scenes.

Some of the famous ones are Ilangeswaran, Chanakkiya Sabadam, Soorapadman, Sisupalan, Indrajith, Sukrachariyar, Naragasooran and Thirunavukkarasar.
