Gábor Klauzál de Szlavovicz (18 November 1804[1] – 3 August 1866[2]) was a Hungarian politician, who served as Minister of Agriculture, Industry and Trade during the Hungarian Revolution of 1848 in the first government of Hungary.

He was a member of the National Assembly of Hungary from 1832 and served as one of the leaders of the liberal opposition on the Diet of 1843–44.

As a minister he represented negotiating, moderate politics, he opposed the extreme politics which wanted to separate from the Austrian Empire, so Klauzál did not support the complete independence.

He stuck out for calling to account of Count Franz Philipp von Lamberg's killers.

During the beginning of the fights, he pulled back to his possessions.
