Abstract
The article discusses the geometry of almost contact hyper and almost contact manifolds hyperkähler. Defines the intrinsic and the associated Obata connection preserving contact almost hypercomplex structure. It is proved that almost contact hyperkähler manifold is $eta$-Einstein manifold.
