Dennis Quaid is moving on with a woman who's half his age, smokin' hot and shares a name with the big man in the red suit.
Her name is Santa Auzina, and they did dinner at El Compadre in L.A. Tuesday night. They were first spotted together in July shortly after Quaid's wife filed for divorce.
Quaid wasn't too talkative when we asked about his pal, Donald Trump, but doesn't really matter when your gf is a babe.
BTW ... She's 30 and he's 62.
