O’Reilly has won the WPS with Sky Blue FC, FA Cup with Arsenal, and NWSL titles with both North Carolina Courage and FC Kansas City.
She accumulated a wild 231 caps in a decade-and-a-half with the USWNT, scoring 42 goals.
Only seven USWNT players have been capped more times than O’Reilly.
On the day before the opening of the 2019 NWSL season, I would like to share that this will be my last season as professional player! It’s been a long and beautiful ride. More goodbyes can come after the season. Until then, we have work to do! See you at the stadium! #couragepic.twitter.com/pu1Ic0yUL6
O’Reilly, 32, is the eighth-highest capped player in USWNT history and retired from the national team in September 2016. She was an integral part of the team which won the 2015 World Cup in Canada, plus she has three Olympic gold medals from the 2004 games in Athens, Beijing in 2008 and London in 2012.
The midfielder scored 47 goals in 231 appearances for the USWNT, while she has also played for the Boston Breakers and most recently the Kansas City Stars in the NWSL.
Speaking about signing for the FA Women’s Super League powerhouse, O’Reilly was delighted to be moving to London.
“Having come over to Arsenal last year to train, I was very impressed with the club,” O’Reilly said. “The facilities are world class and they have a tradition of excellence at the club that I wanted to be a part of, I’m very happy to be here.”
The schedules for the 2017-18 season in both the WSL 1 and 2 were released last week and the opening weekend of the season is on Apr. 22 when O’Reilly’s Arsenal play Notts County.
O’Reilly joins USWNT winger Crystal Dunn in the WSL 1, as she plays for Arsenal’s London rivals Chelsea.
O’Reilly, 32, could return to FC Kansas City after the FAWSL Spring Season. Arsenal holds English internationals Alex Scott and Kelly Smith, as well as former WNY Flash assistant coach Pedro Martinez Losa in the manager’s chair.

She has the seventh-most caps and the sixth-most assists in United States women’s national team history, and she’s also calling it a day.
Excelle Sports is reporting that Heather O’Reilly is retiring at the age of 31. The FC Kansas City player will likely play her final match in September, as the 2015 champs have all-but been eliminated from the playoffs.
O’Reilly had 230 caps, 46 goals, and 54 assists for the USWNT team. She’s one of only a few players to have more than 45 goals and 50 assists (Julie Foudy, Tiffeny Milbrett, Shannon MacMillan, Abby Wambach, Mia Hamm, Kristine Lilly).
One of many successful products of Anson Dorrance’s UNC program, “HAO” spent her club career with New Jersey Wildcats, Sky Blue FC, and Boston Breakers before joining FCKC.
O’Reilly was left off the Olympic roster this summer, named as an alternate. She could’ve been useful — of course hindsight is 20/20 — and it’ll be odd watching more USWNT matches without HAO.
