Il presente articolo è una versione allargata della omonima conferenza tenuta a Milano durante il XVII convegno nazionale UMI nel settembre 2003. L'articolo ha come abiettivo principale quello di presentare una introduzione, il più possibile elementare, ai problemi di razionalità/unirazionalità in geometria algebrica. Avendo come punto di riferimento l'esempio delle ipersuperfici dello spazio proiettivo complesso, in particolare le ipersuperfici cubiche, vengono presentati temi classici e problemi più recenti riguardanti le varietà razionalmente connesse e le famiglie di curve razionali in esse contenute.
This exposition aims to introduce in an elementary way the unirationality/ rationality problems in Algebraic Geometry. The text focuses on the case of the hypersurfaces of a complex projective space. Using this example many classical themes and questions are presented, as well as further problems concerning the class of rationally connected varieties and the families of rational curves contained in such varieties.
