Zeta Celestino Oliveros Gorres (born 18 April 1982) is a Filipino former professional boxer who challenged once for the WBO super-flyweight title.

His real name is a combination of those of his parents; Zeta (mother) and Celestino (father) Gorres.

After winning 13 bouts in a row, he fought Edgar Rodrigo for the Philippine flyweight title on June 1, 2003.

The winner was to face then IBF super flyweight titlist Dimitri Kirilov of Russia who would later be dethroned by Darchinyan on August 2, 2008.

On November 13, 2009, after winning a 10-round bout against Luis Melendez in which he was knocked down with 30 seconds remaining in the final round, Gorres collapsed in the ring and was removed on a stretcher.

Originally, doctors were going to keep him in a medically induced coma for a few days, but Gorres reacted to the treatment much better than anticipated and came out of it.
