We present a new complete near-infrared (NIR, JHK(s)) census of RR Lyrae stars (RRLs) in the globular omega Cen (NGC 5139). We collected 15,472 JHKs images with 4-8 m class telescopes over 15 years (2000-2015) covering a sky area around the cluster center of 60 x 34 arcmin(2). These images provided calibrated photometry for 182 out of the 198 cluster RRL candidates with 10 to 60 measurements per band. We also provide new homogeneous estimates of the photometric amplitude for 180 (J), 176 (H) and 174 (K-s) RRLs. These data were supplemented with single-epoch JK(s) magnitudes from VHS and with single-epoch H magnitudes from 2MASS. Using proprietary optical and NIR data together with new optical light curves (ASAS-SN) we also updated pulsation...
