Jean-Baptiste, Baron Nothomb (French pronunciation: [ʒɑ̃ batist baʁɔ̃ nɔtɔ̃]; 3 July 1805 – 16 September 1881[1]) was a Belgian statesman and diplomat, who served as the prime minister of Belgium from 1841 to 1845.

[2] Nothomb became a member of the national congress, and became secretary-general of the ministry of foreign affairs under Érasme-Louis Surlet de Chokier.

He supported the candidature of the Orléanist Louis, Duke of Nemours, and joined in the proposal to offer the crown to Prince Leopold of Saxe-Coburg, being one of the delegates sent to London.

[2] His Essai historique et politique sur la révolution belge (1838) won for him the praise of Palmerston and the cross of the Legion of Honor from French king Louis Philippe.

[2] In 1840 he was sent as Belgian envoy to the German Confederation, and in 1841, on the fall of the Lebeau ministry, he organized the new cabinet, reserving for himself the portfolio of minister of the interior.
