  We present near-infrared $J$ band photometric observations of the
intermediate polar WX Pyx. The frequency analysis indicates the presence of a
period at 1559.2 $\pm$ 0.2 seconds which is attributed to the spin period of
the white dwarf. The spin period inferred from the infrared data closely
matches that determined from X-ray and optical observations. WX Pyx is a system
whose orbital period has not been measured directly and which is not too well
constrained. From the IR observations, a likely peak at 5.30 $\pm$ 0.02 hour is
seen in the power spectrum of the object. It is suggested that this corresponds
to the orbital period of the system. In case this is indeed the true orbital
period, some of the system physical parameters may be estimated. Our analysis
indicates that the secondary star is of M2 spectral type and the distance to
the object is 1.53 kpc. An upper limit of 30$^\circ$ for the angle of
inclination of the system is suggested. The mass transfer rate and the magnetic
moment 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.
