We present a theoretical calibration of the RR Lyrae period-luminosity (PL) relation in the UBVRIJHK Johnson-Cousins-Glass system. Our theoretical work is based on calculations of synthetic horizontal branches (HBs) for several different metallicities, fully taking into account evolutionary effects besides the effect of chemical composition. Extensive tabulations of our results are provided, including convenient analytical formulae for the calculation of the coefficients of the period-luminosity relation in the different passbands as a function of HB type. We also provide "average" PL relations in IJHK , for applications in cases where the HB type is not known a priori; as well as a new calibration of the M V -[ M /H] relation. These can be summarized as follows: and
