Abstract：
We introduce the concept of K-g-frames in Hilbert spaces and study the essential distinctions between K-g-frames and g-frames. Then we characterize K-gframes by using dual g-frames of special closed subspaces and give a way to construct dual g-frames for special closed subspaces. Finally, we study some properties of K-gframes.
