Lytse Geast (Dutch: Kleinegeest) is a hamlet in Tytsjerksteradiel in the province of Friesland, the Netherlands.

Lytse Geast is not a statistical entity,[2] and the postal authorities have placed it under Tytsjerk.

[1] The hamlet was first mentioned in 1543 as Lutke Geest, and means "little higher elevated sand ground", and was a little island in a bog.

It used to have a bakery and a grocery store, however the supermarkets caused the demise of the retail.

[4] The polder mill Swarte Prinsch was built in Lytse Geast in 1900 and was in commission until 1959.
