On the heels of their huge Super Bowl win, WWE exec Triple H got a custom world heavyweight championship belt done up for the Eagles ... a gold-plated replica of the strap belonging to current WWE champ A.J. Styles.

"To quote Zach Ertz, you’re 'the World Champions' .... so you need a World Title! Congratulations," HHH said.

The belt looks awesome ... but it's worth noting that HHH -- a native of the Boston area -- also got one made for the Patriots last year.

Guess there are no hard feelings.
