We present near-infrared $J$ band photometric observations of theintermediate polar WX Pyx. The frequency analysis indicates the presence of aperiod at 1559.2 $\pm$ 0.2 seconds which is attributed to the spin period ofthe white dwarf. The spin period inferred from the infrared data closelymatches that determined from X-ray and optical observations. WX Pyx is a systemwhose orbital period has not been measured directly and which is not too wellconstrained. From the IR observations, a likely peak at 5.30 $\pm$ 0.02 hour isseen in the power spectrum of the object. It is suggested that this correspondsto the orbital period of the system. In case this is indeed the true orbitalperiod, some of the system physical parameters may be estimated. Our analysisindicates that the secondary star is of M2 spectral type and the distance tothe object is 1.53 kpc. An upper limit of 30$^\circ$ for the angle ofinclination of the system is suggested. The mass transfer rate and the magneticmoment of the white dwarf are estimated to be (0.95 - 1.6)$\times 10^{-9}M_\odot$ yr$^{-1}$ and (1.9 - 2.4)$ \times 10^{33}$ G cm$^{3}$ respectively.
