Bryan Jay Singer (born September 17, 1965) is an American director, producer and writer. He is the founder of Bad Hat Harry Productions and has produced almost all of the films he has directed, as well as multiple television series.

After graduating from the University of Southern California, Singer directed his first short film, Lion's Den (1988). On the basis of that film, he received financing for his next film, Public Access (1993), which was a co-winner of the Grand Jury Prize at the 1993 Sundance Film Festival. In the mid-1990s, Singer received critical acclaim for directing the neo-noir crime thriller The Usual Suspects (1995). He followed this with another thriller, Apt Pupil (1998), an adaptation of a Stephen King novella about a boy's fascination with a Nazi war criminal.
