A musical instrument stand includes a base, a rod mounted on the base, a first mounting seat mounted on the rod, a second mounting seat mounted on the rod and located between the base and the first mounting seat, a plurality of first support members each detachably mounted on the first mounting seat, and a plurality of second support members each detachably mounted on the second mounting seat. Thus, the musical instrument stand has a plurality of first support members and a plurality of second support members for supporting a plurality of musical instruments without having to provide multiple musical instrument stands to support different musical instruments, thereby decreasing the purchase costs, and thereby saving the space of storage.
