  A necessary condition for the reliable modelling of the structure or
evolution of the stars and of their concomitant nucleosynthesis is the
availability of good quality nuclear data in a very wide area of the chart of
nuclides. This short review presents a non-exhaustive list of nuclear data of
astrophysics interest (masses, $\beta$-decays, thermonuclear and
non-thermonuclear reaction rates) for nuclides at the bottom of the valley of
nuclear stability (mainly involved in the modelling of non-explosive phases of
stellar evolution), or for more or less highly exotic nuclides (to be
considered in the description of stellar explosions). Special emphasis is put
on the importance of providing quality nuclear data bases that can be easily
used by astrophysicists.
