Paulo Renato Paim (born 15 March 1950) is a Brazilian steelworker turned politician.

He served as a federal deputy from Rio Grande do Sul for the Workers' Party (Partido dos Trabalhadores – PT) from 1987 to 2002.

He also served as Vice-President of trade union center Central Única dos Trabalhadores (CUT) from 1984 to 1986.

Paim worked on Abramo Eberle and Forjasul metallurgical factories before becoming the president of the Canoas steelworkers trade union on 1981.

Two years later, he became Secretary-General of the Central Única dos Trabalhadores, prior to becoming the Vice-President of that same organization on 1984.

Paim would later spark controversy, in 2001, after he ripped a copy of the Constitution as a protest to a bill seeking to change the Consolidation of Labor Laws.

From 2007 to 2009, he was President of the upper house's Human Rights and Participative Legislation committee.

In 2010, Paim was re-elected Senator for Rio Grande do Sul with almost 34% of the valid votes.

He received over 3.8 million votes; 479,000 more than Governor Tarso Genro, a fellow member of PT.
