The Dekemastate or Dekema State is a stins in the Dutch village of Jelsum, Friesland.

As is the case with many Frisian estates, the Dekemastate grew out of a simple square, defensible stone house, a stins, from the 14th century.

The Camstra family became involved in the conflict between the Schieringers and Vetkopers and as such, in 1492, the old stins was destroyed and almost immediately rebuilt.

Despite the later owners, Unia, Doys, Houth, and Van Wageningen, the estate has retained the name Dekemastate to this day.

[5] In 1791, the heiress Juliana Elisabeth Maria Houth married Gerardus van Wageningen from Dordrecht.

[3] The last Van Wageningen to own the estate, another Gerard, offered hospitality to, among others, the famous detective writer Havank.

In 1990, Gerard van Wageningen founded the Association of Friends and Girlfriends of Dekema State, after which he arranged the transfer of the estate to the foundation Stichting Old Burger Weeshuis in Leeuwarden.
