Maurizio Costanzo (born 28 August 1938) is an Italian television host, journalist, screenwriter and film director.
Costanzo began his career as a journalist, first as a contributing writer to Paese Sera and then as managing editor of the weekly Grazia. In the late 1970s he was the founding editor of the newspaper L'Occhio. Parallel to his career as a journalist, he worked as a radio and TV host, where he became known for his subtle, low-profile irony. His most popular show, Bontà loro was a stable of RAI's programming but he was forced to resign after news broke that he was a member of the Propaganda 2 masonic lodge. Costanzo then moved to Silvio Berlusconi's main TV station Canale 5, where he hosted The Maurizio Costanzo Show, currently the longest-lasting talk show in Italy.
Costanzo was artistic director of Canale 5 until 2009. In 2010 he returned to RAI, presenting the talk show Bontà sua. Since 2011 he also collaborates with Radio Manà Manà.
