Answer
Hi Andrea
It's a pelvic bone (sacrum), but not human. Too short.
I don't really have the expertise to tell you exactly what species it is.
Take it to a natural history museum near where you found it.  They may be able to assist you.
FYI:  Whenever you find large bones on a beach like this, it is best to contact the police or a park ranger before you move it.  If human, it could be part of a crime scene.  Beaches, being isolated places and places where wind and water combine to decompose bodies quickly, are favored locations for criminals to dispose of bodies.
Cheers,
