We have carried out JK near-infrared photometry for the central region of the metal rich globular cluster M71, whose(K, J - K) color-magnitude diagram is presented here. Using two independent methods we derive the distance modulus to M71, 12.89 and 12.86 +/- 0.12 respectively. The former is derived using the HB luminosity for globular clusters having metallicity between -1.0 to photometry of stars in the similar metallicity cluster 47 Tuc. We also estimate the reddening to M71, E(J-K) = 0.13, based on E(B-V) = 0.04 of 47 Tuc.
