Taylor Swift created one awesome moment ... when she brought the U.S. Women's Soccer team on stage in the middle of her concert.

Taylor was playing Met Life Stadium in NJ, and fresh off their parade in NYC -- the World Cup Champs came out while Taylor sang "Style."

Talk about bringing the house down -- the Swifties soaked up the patriotic moment as Alex Morgan loaned the World Cup trophy to Taylor ... just for a few seconds.
