Gosse Ludigman (d. 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,[1] was married to Tetta Brederode and was elected potestaat in 989.[2] In the chronicle of Egmond, by the fifteenth century Carmelite John of Leiden, who 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].
His predecessor was Igo Galema, and after his death the potestaat started to be elected to one-year terms.[3] The next potestaat elected for life was Saco Reinalda in 1150.
