A support for an electronic device includes a mounting apparatus and a supporting apparatus. The mounting apparatus includes a fixing bracket mounted to the main body of an electronic device, an engaging member slidably mounted to the fixing bracket, and a resilient member connected between the fixing bracket and the engaging member. The supporting apparatus includes a connecting bracket detachably mounted to the fixing bracket. When the engaging member is slid relative to the fixing bracket, a stop piece moves away from the connecting hole, and a hook extends through the connecting hole. After the engaging member is released the stop piece moves to the connecting hole to engage with the hook.
