The 20-year-old US international joins the Premier League club on a four-year deal after his contract at Fulham expired, with a compensation package agreed between the two sides due to his age.
Speaking to Bournemouth’s official website, chief executive Neill Blake said: “We've moved swiftly in the window to secure Emerson’s signature and we are delighted to have finalised the deal to bring such a promising young talent to AFC Bournemouth.
"Emerson is a highly rated young player and already boasts international experience, so will be a welcome addition to Eddie and Jason's squad.
“We now look forward to seeing him in action at Vitality Stadium in of our second season in the top flight."
Hyndman, who is the grandson of former FC Dallas head coach Schellas Hyndman, originally joined Fulham from the MLS club in 2011 and went on to feature 28 times for the Cottagers after earning his first-team debut in August 2014, scoring once.
Widely, considered one of the USA’s top talents, the Texas native has already earned two senior international caps and captained the Under-20s to the World Cup quarter-finals in New Zealand last summer.
He surprisingly struggled to break into the Fulham side last term, only making his season debut in December, but the diminutive midfielder made a big impression whenever he was given a chance to show his promise.
Speaking after seeing Hyndman cap a man-of-the-match display in April’s 2-1 victory over Cardiff City by bagging the last-gasp winner, manager Slavisa Jokanovic told the likes of Sky Sports: "He's probably one of the more talented players. I am little bit disappointed with myself that I haven't found more minutes for him this season.
"He probably needs to be a little bit stronger for the Championship. But he's a young guy and he will be a very good footballer for us.”
Fulham ultimately failed to tie Hyndman down to a new deal, however, with the youngster now set to continue his career on the South Coast with Eddie Howe’s side.
Some big clubs were said to be chasing his signature this summer, including Manchester United, Tottenham Hotspur and West Ham United [h/t ESPN FC], but the Cherries should offer him an easier path to first-team football in the immediate future.
He may not walk straight into the line-up, but it likely won't be long before he is making his mark at the Vitality Stadium given his obvious talent.
