Alberto "Abet" Guidaben (born September 14, 1952) is a Filipino retired professional basketball player in the PBA. He was part of the fabled Crispa Redmanizers ballclub that won two Grand Slams, in 1976 and 1983. He was a two-time Most Valuable Player awardee, in 1983 and 1987, joining a select few who are multiple winners of the award such as Bogs Adornado, Ramon Fernandez, Alvin Patrimonio, Benjie Paras, Danny Ildefonso, Willie Miller, James Yap, and June Mar Fajardo.

Guidaben started his career with the Agoho (Mambajao, Camiguin) Pirates and the University of San Jose - Recoletos. Then in 1973, he became part of the Crispa team in the old Manila Industrial and Commercial Athletic Association (MICAA). Later that year, he and Crispa teammate Bogs Adornado were named to the Philippine team that won the 1973 Asian Basketball Confederation (ABC) held in Manila. The two also suited up for the national team that played in the 1974 Mundo Basket (the World Championship) held in San Juan, Puerto Rico. The Crispa-Floro duo were again in the national team skippered by Jaworski for the 1974 Asian Games in Teheran.

In the PBA, Guidaben was a "late-bloomer" with Crispa. During the league's early years, he played in the shadows of his more illustrious teammates like Philip Cezar, Atoy Co and Bogs Adornado. But slowly, his talent as a big man emerged and became one of Crispa's greatest assets. He was already a good rebounder but later developed a strong inside game complimented with accurate off-the-glass jumpers from the perimeter. He was also one of the earliest dunkers in the PBA making the slam dunk vogue in the league a decade before the arrival of highflyers like Samboy Lim, Paul "Bong" Alvarez, Vergel Meneses and Nelson Asaytono. He also had a great rivalry with Toyota's Fernandez which was considered a classic in itself. He won MVP honors in 1983 while with Crispa and 1987 while with San Miguel Beer. Unfortunately, he wound up as a journeyman of sorts having played for eight teams. Aside from Crispa and San Miguel, he also suited up for Manila Beer, Tanduay, Purefoods, Alaska Milk, Pepsi Mega and Shell Rimula X.
