Tomás René Hirsch Goldschmidt (born 19 July 1956) is a leftist Chilean politician and businessman.

During his youth, Hirsch became interested in Silo, an Argentinian writer and leader of a movement that inspired the founders of the Humanist Party.

He was also one of the founders of the Coalition of Parties for Democracy (CPD) and served as Chile's ambassador to New Zealand between 1990 and 1992, under the democratic government of Patricio Aylwin.

Hirsch has also been a major critic of the course the Coalition of Parties for Democracy has taken and was cynical of the euphoria created by the election of the socialist president Michelle Bachelet claiming that her government meant a continuation of the same for most Chileans.

Hirsch has been arrested on a number of occasions by the Chilean police for taking part in demonstrations in support of political causes.
