Bello (c. 755 – 810) was Count of Carcassonne from 790 until his death. He was the founder of the Bellonid Dynasty of Carcassonne and Razès which reached its apex in Wilfred the Hairy, progenitor of the House of Barcelona. It is not known who Bello married, but several children have been suggested for him: Argila and Bera are less likely to have been sons of Bello. Bera is also noted to be the son of William of Gellone, but that is also unlikely based on references detailing William's inheritance.
