'''[[구리]]'''는 자연에서 <sup>63</sup>Cu과 <sup>65</sup>Cu 두 종류의 안정 동위 원소로 이루어져 있으며, 이 밖에 27종류의 [[방사성 동위 원소]]가 알려져 있다. 이들 중 가장 안정한 것은 반감기가 61.83시간인 <sup>67</sup>Cu이며, 이 밖의 방사성 동위 원소는 대부분 1분 이하이다. 원자량 63 미만의 방사성 동위 원소들은 주로 [[양전자 방출]]을 통해 붕괴하는 반면 원자량 65를 초과하는 동위 원소는 주로 [[베타 붕괴#음의 베타 붕괴(β-)|음의 베타 붕괴(β<sup>-</sup>)]]를 한다. <sup>64</sup>Cu는 두 가지 붕괴를 모두 할 수 있다.<ref name="nubase">{{저널 인용 |author=G.

구리의 표준 원자량은 63.546(3)[[원자량 단위|u]]이다.
