  In this work we derive a gravastar model in Randall-Sundrum II braneworld
scenario. Gravastars (or gravitationally vacuum stars) were proposed by Mazur
and Mottola as systems of gravitational collapse alternative to black holes.
The external region of the gravastar is described by a Schwarzschild
space-time, while its internal region is filled by dark energy. In between
there is a thin shell surface with ultrarelativistic matter (sometimes referred
to as stiff matter). We obtain solutions for some physical quantities of the
braneworld gravastars. Those are compared to original Mazur-Mottola results as
well as with some gravastar solutions in alternative gravity theories. The
consequences of the braneworld setup in gravastar physics is deeply discussed.
