Ernesto Jose Francisco "Joey" Cuerva Loyzaga (born September 23, 1961) is a Filipino retired professional basketball player.
Loyzaga broke into the hoops limelight as a Red Cub for San Beda College in the National Collegiate Athletic Association (Philippines).
He moved from Mendiola to the Legarda campus of the Arellano University because of the strict policy of the NCAA regarding participation in commercial leagues.
Loyzaga was dropped from the Añejo (formerly Ginebra) lineup beginning the 1990 PBA season and was picked by expansion franchise Pop Cola from the pool.
Loyzaga did return to Ginebra for one season in 1994 but his career was already downhill at that point, he managed to stage a comeback four years later with Alaska.
