We report the discovery of a transiting hot Jupiter around OGLE-TR-111, from our radial velocity follow-up of OGLE transiting candidates in Carina. The planet has a mass of $0.53 \pm 0.11$  $M_{\rm J}$ and a radius of 1.0+0.13-0.06  $R_{\rm J}$. Three transiting exoplanets have already been found among OGLE candidates, all with periods near 1.5 days. The planet presented here, with P=4.0 days, is the first exoplanet detected by transits with the characteristics of a "normal" hot Jupiter, as found in abundance by radial velocity surveys. The radius of OGLE-TR-111b and the scarcity of hot Jupiters detected among OGLE transit candidates tend to indicate that the case of HD 209458b, with a radius of 1.4  $R_{\rm J}$, is exceptional, with most hot Jupiters being smaller.
