Nagalingam Ethirveerasingam (24 August 1934 – 18 April 2024) was a Sri Lankan athlete who represented Ceylon at the 1952 and 1956 Summer Olympic Games.

He was co-record holder at the 1954 Manila Asian Games after jumping the same height (1.95 meters) as the gold, silver, and bronze jumpers, but came fourth due to having more misses than the other athletes.

He taught at universities in Sierra Leone, Papua New Guinea, Nigeria and Sri Lanka.

In later years whilst lecturing in Sierra Leone, he captained the university cricket team in the local cricket tournament and in 1973 was appointed vice captain of the national team that played against the neighbouring country of Gambia.

Ethirveerasingam received a PhD and wrote several books, one being The Effect of Advance Presentation of Organizers On Complex Verbal Learning and Retention by Vocational Agriculture Students in New York State.
