Sidse

Sidse is a feminine given name of Danish origin. It is primarily used in Denmark and among Danish-speaking communities, but it has also appeared in other Nordic countries and among expatriate populations. The exact origin of the name is not firmly established; it is commonly treated as a distinct Danish given name, though some sources suggest it may be related to longer forms such as Sidsel or Sidonie and can function as a diminutive in informal use.

In Danish culture, Sidse has been borne by several individuals in the arts and public life, with the best known being Sidse Babett Knudsen (born 1968), a Danish actress acclaimed for her lead role in the political drama Borgen and for appearances in international productions including Westworld.

Today, Sidse remains a recognizable, though relatively uncommon, name within Denmark. It is occasionally encountered in Danish media and literature as a marker of Danish identity, and it continues to be used by families who favor traditional or distinctly Danish given names.
