Ximeno (Jimeno) the Strong () was an 8th-century military chieftain.
He rebelled against Abd al-Rahman I, the emir of Córdoba, to whom he had to submit in the year 781, promising to pay him the corresponding tribute. He was probably the son of the King GarcàXiménez of Sobrarbe, and he had a brother, Fortún Garces. He had two sons, ÃÂñigo and GarcÃÂa Jiménez or Ximénez (names that are repeated in the Jiménez dynasty).
