A wind instrument stand includes a base and a holding unit. The base includes a front support frame and a rear support frame. The holding unit includes a support rod rotatably mounted on the front support frame, two holding members pivotally mounted on the support rod respectively, and two torsion springs each biased between the support rod and the respective holding member. Thus, when the neck of the saxophone is placed between the holding members, the holding members are pivoted and moved toward each other by the weight of the saxophone to clamp the neck of the saxophone, so that the neck of the saxophone is clamped between the holding members exactly and stably to prevent the saxophone from being detached from the holding members due to an accidental vibration or hit.
