Matteo Martinolich (10 February 1860 - 23 December 1934) was an American master shipbuilder. He was the first to use Mississippi pine in the building of seagoing vessels, which was approved by the Marine Underwriters.
Born in Mali Lošinj, Croatia (at the time part of the Austro-Hungarian Empire), the son of Francesco Stanislao Martinolich and Maria Dominica Merlo, he initially studied naval architecture and received training in carpentry at the Austrian naval shipyards in Pola (present-day Pula, Croatia). At that time, Pola was the chief naval base of the Austro-Hungarian Empire.
He arrived in the United States at the age of 23, landing in New Orleans with his brother Francesco (Frank) Martinolich. They settled shortly after in DeLisle, Mississippi, where Matteo worked for local shipbuilder Antonio Pavolini, originally from Italy. Matteo married Antonio's oldest daughter, Johanna, in 1885.
From 1907-11, Martinolich also worked with the U.S. Army Corps of Engineers on the Chattahooc
