Tito Montilla Dupaya (January 1, 1922 – April 1, 1989) was a Filipino industrialist, businessman, and politician who served as the representative for Cagayan's 3rd congressional district in the Philippine House of Representatives from 1987 to 1992. He previously represented Cagayan's 1st district from 1961 to 1973.
Tito Montilla Dupaya was born on January 1, 1922, in Barrio Catugan, Lal-lo, Cagayan, to Panteleon Dupaya and Nena Montilla. He attended Lal-lo Elementary School for his primary education and Cagayan High School and Cagayan Valley Atheneum for his secondary education. He later earned a Bachelor of Science degree in Foreign Service from Far Eastern University.
After graduating from college, Dupaya entered business, serving as manager and proprietor of the import-export firm Dupaya Trading, president of the Lal-lo Rural Bank, and proprietor of the Lal-lo Rice Mill, Transportation, and Ice Plant companies. He also worked as a log exporter.

Dupaya first entered politics in 1961, when he was elected to the House of Representatives, representing Cagayan's 1st congressional district under the Nacionalista Party in the 5th Congress. During his first term, he authored more than 300 bills focused on local development in his constituency, including the establishment of educational institutions, public markets, and health facilities. He was re-elected in 1965 under the Liberal Party. During his second term, he allocated his salary to scholarships for deserving students from his district. During the 6th Congress, he served as chairman of the House Committee on Reparations, vice chairman of the Committee on Public Lands, and a member of six other committees.
In 1969, Dupaya was re-elected to a third term but was unable to complete it following the abolition of Congress in the aftermath of President Ferdinand Marcos's declaration of martial law and the ratification of the 1973 Constitution.
In 1984, Dupaya ran for the Regular Batasang Pambansa under the United Nationalist Democratic Organization, representing Cagayan, but lost.
When Congress was restored in 1987, Dupaya was elected representative of Cagayan's newly created 3rd congressional district. During the 8th Congress, he served as vice chairman of the House Committee on Agriculture and Food.
Dupaya died in office on April 1, 1989, from heart failure.
Dupaya was married to Teresa Javier, who served as governor of Cagayan from 1964 to 1980 and in 1987. They had five children.
