Piero Marrazzo (born 29 July 1958) is an Italian journalist and politician.

He was a political activist during his youth, leading towards reformist socialism, and obtained a degree in jurisprudence.

He went on to become a prominent TV journalist, working for twenty years for RAI, on programmes such as TG2 and TG3, heading the Tuscany journalistic department of RAI, working with Giovanni Minoli (on programmes such as "Cronaca in Diretta", "Drugstories", and "Format"), and finally becoming the anchorman for eight consecutive years of "Mi Manda Rai Tre", for which he is most remembered.

[citation needed] In November 2004 he left his job to run for presidency of Lazio as the candidate of centre-left coalition L'Unione; he won the April 2005 regional elections attracting 50.7% of votes.

He suspended himself from his role on Saturday 24 October 2009, after 4 carabinieri officers allegedly tried to blackmail him with video footage, purporting to reveal him in a bedroom with a transsexual prostitute, where a limited quantity of cocaine was also present.
