Abstract: Analysis of all available infrared JHK photometry was performed to determine interstellar extinction, distance and basic parameters of the cool component in the symbiotic nova V1016 Cyg. The cool component is a Mira variable of the spectral type M 7 and pulsation period 474 ± 2 days. Its mass is 0.81 ± 0.20 M, mean radius 485 ± 40 R, mean effective temperature 2450 ± 150 K and luminosity 7600 ± 100 L. The distance to symbiotic system was determined to be 2.93 ± 0.75 kpc.
