Mario Vergara (16 November 1910 – 24 May 1950) was an Italian Catholic priest of the Pontifical Institute for Foreign Missions who was killed in Burma (now Myanmar) in 1950.

Vergara was entrusted a small village and it was there that he ensured that there be regular catechesis lessons and the celebration of the sacraments.

When World War II started, Vergara was interned in a British concentration camp in India in 1940.

He returned to Burma in 1947 and continued his mission there, and met the catechist Isidore Ngei Ko Lat.

Pope Francis approved his and Isidoro Ngei Ko Lat's martyrdom on 9 December 2013, thus, allowing for their beatification.
