CDF and D0 have measured the effective leptonic weak mixing angle $$sin^2 \theta^{lept}_{eff}$$ , using their full Tevatron datasets. This note describes the Tevatron combination of these measurements, and the zfitter standard model-based inference of the on-shell electroweak mixing angle $$sin^2 \theta_W$$, or equivalently, the W-boson mass. The combination of CDF and D0 results yields: $$sin^2 \theta^{lept}_ {eff}$$ = 0.23179 ± 0.00035, and $$sin^2 \theta_W$$ = 0.22356 ± 0.00035, or equivalently, $$M_W$$(indirect) = 80.351 ± 0.018 GeV/$c^2$.
