We report the discovery from WASP-South of a new Jupiter-like extrasolar planet, WASP-16b, which transits its solar analog host star every 3.12 days. Analysis of the transit photometry and radial velocity spectroscopic data leads to a planet with R $_p$ = 1.008 plusmn 0.071 R $_Jup$ and M $_p$ = 0.855 plusmn 0.059 M $_Jup$, orbiting a host star with R $_*$ = 0.946 plusmn 0.054 R $_sun$ and M $_*$ = 1.022 plusmn 0.101 M $_sun$. Comparison of the high resolution stellar spectrum with synthetic spectra and stellar evolution models indicates the host star is a near-solar metallicity ([Fe/H] =0.01 plusmn 0.10) solar analog (T $_eff$ = 5700 plusmn 150 K and log g = 4.5 plusmn 0.2) of intermediate age ($ = 2.3$^+5.8$ $_-2.2$ Gyr).
