John I of Viennois

John I (1264–1282) was dauphin of Viennois and count of Albon from 1269, succeeding his father Guigues VII when he was only five. His mother Béatrice of Faucigny ruled as regent, and a 1270 convention named Duke Robert II of Burgundy as his tutor.

When his mother married Gaston VII of Béarn in 1273, Robert became regent of the Dauphiné. John died in 1282 after a fall from his horse, aged eighteen and without an heir, so his lands passed to his sister Anne.
