The Star Awards for Best Supporting Actor is an award presented annually at the Star Awards, a ceremony that was established in 1994.
The category was introduced in 1995, at the 2nd Star Awards ceremony; Xie Shaoguang received the award for his role in Larceny of Love and it is given in honour of a Mediacorp actor who has delivered an outstanding performance in a supporting role.
