The Battle of Picotin, between Ferdinand of Majorca and the forces of Matilda of Hainaut, ends in victory for Ferdinand.

The Battle of Picotin was fought on 22 February 1316 between the Catalan forces of the infante Ferdinand of Majorca, claimant to the Principality of Achaea, and the forces loyal to Princess Matilda of Hainaut, comprising native levies from the barons loyal to the Princess as well as Burgundian knights. The battle ended in a crushing victory for Ferdinand, but he was later engaged and killed by the troops of Matilda's husband, Louis of Burgundy, at the Battle of Manolada.

Ferdinand of Majorca was an infante of the Kingdom of Majorca; he was born at Perpignan, the third son of King James II. He was Viscount of Aumelas and Lord of Frontignan from 1311 and claimed the title of Prince of Achaea from 1315.

Matilda of Hainaut, also known as Maud and Mahaut, was Princess of Achaea from 1316 to 1321. She was the only child of Isabella of Villehardouin and Florent of Hainaut, co-rulers of Achaea from 1289 to 1297. After Florent's death in 1297, Isabella continued to rule alone until she remarried to Philip of Savoy in 1300. Per arrangements made with King Charles II of Naples, Isabella was not allowed to marry without his consent and after Philip failed to adequately participate in the king's campaigns against Epirus, Charles in 1307 revoked their rights to Achaea. Matilda, just fourteen years old, tried to press her claim as their heir but was refused by the bailiff Nicholas III of Saint Omer, who instead chose to wait for orders from Naples. Shortly thereafter, Charles appointed his favorite son, Philip of Taranto as the new Prince of Achaea.
