Wymbritseradeel was a rural municipality in the Dutch province of Friesland from 1984 until 2011. An earlier type of municipality of the same name existed from 1500 until 1984. Wymbritseradeel was formed from the division of the medieval district of Waghenbrugghe. The grietenij of Wymbritseradeel was created in 1500 as Frisian cities became independent and several grietenij were split on the south side of the area. The boundaries of Wymbritseradeel remained unchanged until 1984. From 1625 until the introduction of the municipal law in 1851, the grietman of Wymbritseradeel lived in the stins of Epemastate in IJsbrechtum.
