Witmarsum (West Frisian: Wytmarsum) is a village in the northern Netherlands.

The village was first mentioned in the 13th century as Witmarsum, and means "settlement of Witmer (person)".

[4] Witmarsum is a terp (artificial living hill) village which developed in the early middle ages.

The village used to concentrate on the terp, along the canal and along the road from Bolsward to Harlingen.

[5] The Dutch Reformed church was built in 1633 as a replacement of its medieval predecessor, because it was damaged by a lightning strike.
