Wolf Henrik von Kalnein (died 27 August 1690) was a Prussian noblemen in Danish service.

Having been in Brandenburg, French, and Dutch service, Kalnein came into Danish service in 1677, as a captain in the Regiment von Lehndorf, loaned by the Elector of Brandenburg to the King of Denmark; together with Ernst von Tettau and other brother officers.

He was therefore made royal commissioner with the task of investigating irregularities allegedly committed by the Danish East India Company governor of Tranquebar, Axel Juel.

Kalnein travelled to India on three merchant-men, accompanied by some military specialists who would restore the defences of Fort Dansborg.

Returning to the army as a colonel in 1688, Kalnein was the following year made commander of Prince Frederick's Battalion in the Danish Auxiliary Corps in Ireland.
