Jean Claude Balthazar Victor de Chantelauze (10 November 1787 – 10 August 1859) was a French lawyer and politician who was appointed Minister of Justice in the last weeks of the Bourbon Restoration.

Jean Claude Balthazar Victor de Chantelauze was born in Montbrison, Loire, on 10 November 1787.

He became known after the first Bourbon Restoration in 1814 by a very liberal brochure on the draft constitution that the conservative senate had to submit to King Louis XVIII.

At the opening session of 1830 Chantelauze was supported by the government in a bid to become President of the Chamber, winning 116 votes.

When Jean Joseph Antoine de Courvoisier resigned, King Charles X offered the Ministry of Justice to Chantelauze, who accepted on 19 May 1830 after much hesitation.
