Introduction: Mass segregation as primordial or dynamical phenomenon in star clusters is studied in populous clusters of the LMC from HST Data Archive Center. The extended dynamical range of HST towards the low mass stars allows the study of the spatial distribution of the various masses in the clusters. We selected non typical cluster cases in order to explore the dynamical behaviour in more complicated environments. Methods: We have used data from the HST archive and reduced them with HSTphot. Star counts were performed to obtain the spatial distribution of various luminosity stars and we produced the Mass Functions of the clusters at different clusters´ distances. Results: Two typical clusters selected (one binary, NGC2011, and one very elliptical, NGC1711) have shown that: a: their density profiles indicate a central concentration of the most massive stars in both clusters b: their Mass Functions illustrate a different slope at the central areas of each cluster compared to the Mass Functions of the outer ones Discussion: NGC1711 a young (age ~5x10^7 yr), very elliptical LMC cluster shows evidence of mass segregation with the massive stars (about 6M&sun;) located at the central area of the cluster. NGC2011 a young (age ~10^7 yr), typical double cluster is also investigated and evidence of mass segregation is also observed, with the massive stars reaching about 16M&sun;. The distribution of low mass stars (less than 1M&sun;) is also discussed.
