Mu Geminorum (μ Gem μ Geminorum) is the Bayer designation for a star in the northern constellation of Gemini. It has the traditional name Tejat Posterior which means back foot because it is the foot of Castor one of the Gemini twins. This name was formerly applied to an asterism consisting of this star along with γ Gem (Alhena) ν Gem η Gem (Tejat Prior) and ξ Gem (Alzirr).
