We have compiled the near infrared Point Source Catalogue (PSC) towards the Magellanic Clouds (MCs) extracted from the data obtained with the Deep Near Infrared Survey of the Southern Sky - DENIS (Epchtein et al. [1997]). The catalogue covers an area of of $19.87\times 16$ square degrees centered on $(\alpha,\delta)=(5^{\rm h}27^{\rm m}20^{\rm s}$, $-69\hbox{$^\circ$ }00\hbox{$^\prime$ }00\hbox{$^{\prime\prime}$ })$ for the Large Magellanic Cloud (LMC) and $14.7\times 10$ square degrees centered on $(\alpha,\delta)=(1^{\rm h}02^{\rm m}40^{\rm s}$, $-73\hbox{$^\circ$ }00\hbox{$^\prime$ }00\hbox{$^{\prime\prime}$ })$ for the Small Magellanic Cloud (SMC) at the epoch J2000. It contains about $1\,300\,000$ sources towards the LMC and $300\,000$ sources towards the SMC each detected in at least 2 of the 3 photometric bands involved in the survey (I, J, $K_{\rm s}$). $70\%$ of the detected sources are true members of the Magellanic Clouds, respectively and consist mainly of red giants, asymptotic giant branch stars and super-giants. The observations have all been made with the same instrument and the data have been calibrated and reduced uniformly. The catalogue provides a homogeneous set of photometric data.
