CKV Unitas (Christelijke Korfbal Vereniging Unitas) is a Dutch korfball club located in Harderwijk, Netherlands.

During the first years after the club has been established it did not have its own clubhouse and locker rooms and had to improvise in order to be able to actually complete the competition.

The club made extensive use of school korfball to recruit new members.

For the first time in the club's history, Unitas reached the Hoofdklasse final in the indoor competition in the 2021–2022 season.

Unitas won the final against HKC, earning promotion to the Korfbal League, the highest Dutch indoor korfball competition.
