Joseph-Marie-Bruno-Constantin, Baron Kervyn de Lettenhove (17 August 1817 – 3 April 1891) was a Belgian historian and politician.

The cabinet appointed as governor of Limburg one Decker, who had been entangled in the financial speculations of Langand-Dumonceau by which the whole clerical party had been discredited, and which provoked riots.

The cabinet was forced to resign, and thereafter Kervyn de Lettenhove devoted himself entirely to literature and history.

[1] He was also a correspondent of foreign scientific societies, and preëminent in his own country as an investigator of the national antiquities.
