Bradley, who took over Toronto in November 2021, was relieved of duties after a run of poor results that has the club second from the bottom of the Eastern Conference ahead of only Inter Miami with a 3-7-10 record (win-loss-draw).
"Bob has been a consummate professional with Toronto FC and we thank him for his passion and tireless work during his time here. We are all disappointed that we were not able to achieve the results we expected," said Toronto FC President Bill Manning in a statement.
Terry Dunfield (41), who was in charge of Toronto FC under-17 academy team, has been named interim head coach.
The well travelled Bradley has coached in England, Egypt, Norway, the Netherlands along with five MLS clubs.
He was also head coach of the US men's national team from 2006-11 guiding them to the knockout round of the 2010 World Cup.
