Gosse Ludigman (elected 989 died in 1000) was a legendary potestaat (or elected governor) of Friesland, now a province of the Netherlands. He does not appear in sources until hundreds of years after his supposed life.
Gosse lived at Staveren, and was married to Tetta Brederode. In the chronicle of Egmond, by the fifteenth century Carmelite John of Leiden, he said. "Hij leefde ten tijde van graaf Arnoud , die zichzelf graaf van Oostergo en Westergo noemde zonder ooit enig gezag te hebben uitgeoefend". He lived at the time of Count Arnoud who proclaimed himself count of Oostergo and Westergo without ever having any authority.
