Joseph Theodore Leslie "Squizzy" Taylor (29 June 1888 – 27 October 1927) was an Australian gangster from Melbourne. He appeared repeatedly and sometimes prominently in Melbourne news media because of suspicions, formal accusations and some convictions related to a 1919 gang war, to his absconding from bail and hiding from the police in 1921–22, and to his involvement in a robbery where a bank manager was murdered in 1923.
