Mardiros Altounian (1889–1958) was an Armenian-Lebanese architect. He designed the Lebanese Parliament Building in Beirut (1931), the Abed clock tower (1934), Azounieh sanitorum in Chouf, and Melkonian Benefactors' Mausoleum in Cyprus (with French-Armenian sculptor Leon Mouradoff).^[1][2][3] Altounian was French-Armenian. The mausoleum replaced an older wooden trellis monument and was completed in 1956.

Altounian graduated from the Ecole des Beaux Arts in Paris, France, in 1918.^[1]
