The 35-year-old actress and 32-year-old actor, who announced their engagement last year, tied the knot before an intimate gathering of family and friends at sunset on Saturday.
"Ginnifer and Josh seemed very relaxed and happy," a source told E! News. "They were surrounded by their nearest and dearest friends and kept it very intimate and simple."
The couple is also expecting their first child together.
Dallas, who gushed over his now-wife back 2012, told People that his love for Goodwin "hit me like a blinding light."
"I thought, 'I'm in trouble now,'" he said at the time.
