Muniswamy Mudaliar (Tamil: முனிசாமி முதலியார்) (died 23 December 1942) was an Indo-Fijian politician who was a member of the Legislative Council from 1932 to 1937.

However, after a rebel Indo-Fijian put themselves forward as a candidate for the Southern Constituency, Deo nominated K. B. Singh to oppose them.

In February 1933, the Secretary of State informed the Legislative Council that it was impracticable to have common roll.

Singh took his seat in the Legislative Council, contrary to Vishnu Deo's instructions and the two evaded the common roll issue.

They were denounced in public meetings organised by Deo and his associates, but Mudaliar was rewarded by the Government by being made Fiji's first Indo-Fijian Justice of Peace.
