Manuel José Ossandón Irarrázabal (24 August 1962) is a Chilean agricultural technician and politician. Since March 2022, he has served as a senator of the Republic, representing the 7th Constituency (Santiago Metropolitan Region), elected in the 2021 parliamentary elections, for the 2022–2030 legislative term. Previously, he held the same office, representing the 8th Constituency, Santiago Oriente, during 2014–2022. Since March 26, 2025, he has served as President of the Senate of Chile.

He is a member of the National Renewal (RN) party, although he remained independent from July 2016 to July 2017, when he returned to the party. He served as mayor of the Santiago communes of Pirque for two consecutive terms, from 1992 to 2000, and Puente Alto for three consecutive terms between 2000 and 2012. His career has been marked by a social-conservative line.

In July 2017, he was a presidential pre-candidate for the center-right coalition Chile Vamos, running in the coalition’s primary, where he placed second behind former president of the Republic, Sebastián Piñera.
