Anthony Flanagan (born 11 April 1972 as Tony Bonello) is an English actor most widely known for his portrayal of policeman Tony in Channel 4's comedy-drama series Shameless.

Flanagan was born in Stockport, Cheshire. At school he was called Anthony Bonello. After leaving Grange Comprehensive School, in Oldham, he worked as a joiner. At 16 he went to London, taking on occasional odd jobs and for a time slept on the streets. Flanagan has described this as "a very bad period". Flanagan decided to become an actor after seeing a friend of his sister perform at RADA.
