[[파일:초산나트륨.png|섬네일|아세트산나트륨]]
'''아세트산 나트륨'''(Sodium acetate) 또는 '''초산 나트륨'''(醋酸-)은 [[아세트산]]의 [[나트륨]]염으로, 분자식은 CH3COONa이다. 무색의 가루 또는 덩어리이며 공기중에서 쉽게 [[풍화]]된다. 밀도는 1.528g/cm3이고, 끓는점은 881.4&nbsp;°C이다. 인체에 크게 유해한 점은 없다. 디하이드로아세트산나트륨은 식품첨가물로 사용된다. 촉감은 [[염화 나트륨|염화나트륨]](소금)과 비슷하다.

과포화 상태의 아세트산 나트륨 수용액에 압력을 가해주면 순식간에 고체로 변해버리는데, 이때 많은 양의 열을 방출하기 때문에 주로 똑딱이 손난로를 만드는 데 사용된다.
