Knud Pedersen Porse or Canute Porse (died 30 May 1330) was a medieval Danish nobleman and Duke of Samsø, Duke of Halland, and Duke of Estonia.
Porse was the son of Peder Knudsen Porse, a Danish nobleman who was involved in the murder of King Eric V of Denmark and thus exiled together with his family in Sweden since 1286, where he had prospered.
On 21 June 1327 Porse married Ingeborg Haakonsdatter of Norway (1301–1361), who was Duchess of Södermanland by her first marriage. They had three children:
- Haakon Knudsen Porse, Duke of Halland (died 1350)
- Knud Knudsen Porse, Duke of Halland (died 1350)
- Birgitta Knudsdatter Porse[1] (m. Jon Haftorsson and had issue)
