Aims. We present new near-infrared (NIR) light-curve templates for fundamental (FU, J, H, K-S) and first overtone (FO, J) classical Cepheids. The new templates together with period-luminosity and period-Wesenheit (PW) relations provide Cepheid distances from single-epoch observations with a precision only limited by the intrinsic accuracy of the method adopted.
