Alex Mallari Jr is a Canadian actor of Filipino descent. He was born on February 19, 1988 in the Philippines, but was raised in Scarborough, Toronto, Ontario, Canada. Mallari was competitive at a national level in Tae Kwon Do, for which he has a third-degree black belt. He was twice a Junior Canadian National Tae Kwon Do champion. However, he gave that up when he was 13. He then took up basketball with the intention of turning professional but an injury prevented him from pursuing that career.
While attending Criminology at the University of Toronto, Mallari decided to pursue acting. His first notable acting role was as Four/Ryo Ishida in the Syfy television series Dark Matter, based on the comic book series of the same name. The series ran for three seasons from 2015 to 2017.
He has since appeared in several films and televisions series, including CBC's comedy series Workin' Moms (2020–2022), Netflix's dramedy series Ginny & Georgia (2021–present), and the Netflix films The Adam Project (2022) and Code 8: Part II (2024).
