  We examine the muon g-2 anomaly of the mirror twin Higgs models with the
joint constraints of the Higgs global fit data, the precision electroweak data,
the leptonic flavor changing decay \mu \to e\gamma decays, and the mass
requirement of the heavy gauge bosons. It is concluded that the muon g-2
anomaly is very sensitive to two parameters: 0.03\leq y_{\nu l}\leq 0.09 and
0.4\leq y_t\leq 0.8, while other parameters are almost irrelevant.
