Jan I van Cuijk

Jan I van Cuijk (c. 1230 – 13 July 1308) was a Brabantine noble, knight and diplomat, and lord of Cuijk. In 1288 he fought for the Duke of Brabant at the Battle of Worringen, where he was praised as one of the bravest knights.

In 1294 King Adolf of Nassau sent him as envoy to Edward I of England to negotiate an alliance, and in 1296 he led the baronial conspiracy that overthrew Count Floris V of Holland. His son Jan II succeeded him.
