To provide a medical observation apparatus and a medical observation system that are excellent in manipulability and favorable for downsizing.SOLUTION: A medical observation apparatus comprises: an observation unit including an image capture unit to capture an image of an object to be observed； and a support unit supporting the observation unit in a rotationally movable manner around a second axis that is oriented in a different direction than a first axis that is along an optical axis, toward a direction different than the optical axis direction from a location farther from one end of the image capture unit in the optical axis direction than the center of gravity of the observation unit. The center of gravity is located near the intersection of the first axis and the second axis, or is located nearer to the one end than the intersection is.SELECTED DRAWING: Figure 2【課題】操作性に優れて小型化にも好適な医療用観察装置および医療用観察システムを提供する。【解決手段】被観察体を撮像する撮像部を有する観察部と、撮像部の光軸方向の一端に対して観察部の重心より遠くの位置から前記光軸方向と異なる方向に向けて、光軸に沿った第１軸と異なる方向の第２軸のまわりに回動可能な態様で前記観察部を支持する支持部と、を備え、重心は、第１軸と第２軸の交点の近傍に位置する、または該交点より一端から近くに位置する。【選択図】図２
