Chris Evans is a HUGE New England Patriots fan ... but says he's seriously considering "cutting ties" with Tom Brady if the QB still supports "dumb sh*t" Donald Trump.
Evans -- who was born in Boston -- is one of the most famous Patriots celebrity fans. He's been to multiple Super Bowls and has hung out with Pats owner Robert Kraft.
But the "Captain America" actor is also VERY anti-Donald Trump and told the Hollywood Reporter it would be very difficult to continue rooting for Tom Brady if TB12 is still supporting POTUS.
