Alfonso II of Toulouse[note 1] (died 1175/1189 or later) was an Occitan nobleman and Count of Toulouse, Duke of Narbonne and Marquis of Provence from 1148 until his death.
After the death of Alfonso I, his eldest son and Alfonso II's brother Raymond V inherited the County of Toulouse and the Marquisate of Provence.
Immediately after his accession, Raymond V made his brother Alfonso co-ruler with him.
[2] Sometime between 1175/1189, Alfonso confirmed the donation of King Henry II of England to Chartres Cathedral.
He likely predeceased his brother Raymond, who died in 1194 and became sole ruler upon Alfonso's death without heirs.
