Tiago Pires, also known by his nickname "Saca", is a recently retired professional surfer from Portugal.

He was the first male Portuguese surfer to qualify for the WSL Elite Tour.

In 1996, when he was 16, he joined the national circuit, where he met José Seabra who later became his coach.

A year later, he got his first WQS win at Vila Nova de Gaia.

In 2013, a serious knee injury halted his progression, and his CT run came to an end after the 2014 season.
