Allan Alaalatoa (born 28 January 1994) is an Australian rugby union player who plays as a prop for the Brumbies in Super Rugby.
Alaalatoa hails from a rugby family with father Vili playing for Samoa in the 1991 Rugby World Cup and brother Michael also going on to play professionally with the New South Wales Waratahs. His big break came ahead of the 2014 Super Rugby season when he was named in the Brumbies extended playing squad. He didn't get any game time during the regular season, but surprisingly was given a debut off the replacements bench in the Brumbies 32-30 victory over the Chiefs during the Super Rugby playoffs.
