Gil Juco Puyat Sr. (September 1, 1907 – March 22, 1981) was a Filipino politician and businessman who served as a Senator of the Philippines from 1951 until 1972, when President Ferdinand Marcos shut Congress down and declared Martial Law, and as Senate President from 1967 to 1972, usurping the seat of Arturo Tolentino.

Even as a student, he was already immersed in intricate operations of finance and expense, of capital and production, and of management labor handling.

Puyat's skill in managing the family business caught the eye of the late President Manuel L. Quezon.

[citation needed] In 1953, he received a plaque from the Community Chest of Greater Manila for “outstanding services as one of the founders, first president and first campaign fund chairman“ of the body.

The Philippine Institute of Public Opinion (PIPO) awarded him a certificate of honor for demonstrating national leadership in business, economics, the civic and political fields and for his distinguished service to the youth.

He was trained early in life by his father, Don Gonzalo, in the trade of manufacturing billiard tables and bowling alleys.

[citation needed] The Gil Puyat station on the LRT Line 1, located along the avenue, is also named after him.
