John P. Angelos (born May 14, 1967) is an American businessman who managed the Baltimore Orioles from 2020 until its sale to David Rubenstein in 2024,[1] leading the club's front office and overseeing day-to-day business operations.

Angelos managed the day-to-day business operations of the Baltimore Orioles, overseeing marketing and advertising, branding and promotion, major corporate sponsorship sales and ticket sales, governmental and public affairs, media and public relations, ballpark facility design and management, event operations, concessions rights negotiation and self-operation.

[3][4][5] On August 7, 2023, a tweet published by Matt Jergensen claimed that Angelos was responsible for the absence of Kevin Brown, lead broadcaster for the Orioles, since July 23.

[6] Awful Announcing on Twitter added a video clip,[7] claiming Brown's comments prior to July 23 on the Orioles' past poor performance against the Tampa Bay Rays were to blame.

"[9] This sparked general outrage by fans, journalists, and fellow broadcasters across the MLB, including rival teams of the Orioles such as the New York Yankees.

In response, "A senior Orioles official communicated to [Awful Announcing] 'We don’t comment on personnel matters' and 'We look forward to hearing Kevin’s voice soon.'

Angelos served as a lead negotiator with various Florida communities over renovating the team's facility in Fort Lauderdale and ultimately relocating Orioles' spring training to Sarasota.

"[29] In late 2013, the Tampa Bay Business Journal heralded the results of the partnership in a cover story, describing the deal as a home run for Sarasota's tourism industry.

[38] He and his brother, attorney Louis Angelos, led a delegation of team and baseball officials to Havana to negotiate the final agreement for the two-game series.

In various speaking engagements, interviews and in a cover story with SportsPro Magazine, Angelos has described the many disadvantages for small and mid-market teams within Major League Baseball's decentralized model.

[51] Angelos often points to the NFL's centralized revenue-sharing model and parity mechanisms as a key foundation of the league's enormous success, especially in smaller markets.

Throughout the season, special guests have included Hall of Fame trainer Nick Zito, elite trainers Kiaran McLaughlin, Chad Brown, Dale Romans and Ian Wilkes, Breeder's Cup champion jockeys Rosie Napravnik and Ramon Dominguez, Washington Post journalist, and creator of the industry-changing Beyer Speed Figures, Andy Beyer, and Daily Racing Form publisher and noted author and columnist, Steve Crist.

In its first year, the program had strong local advertising support from a variety of corporate, nonprofit and media sponsors including Parting Glass Racing, the Christopher Dailey Foundation, ESPN Radio 104.5, Thoroughbred Building Solutions, Special Olympics New York, Hattie's Restaurant, New York Thoroughbred Breeders Inc., Daily Racing Form, Permanently Disabled Jockey's Fund, Saratoga Hospital Foundation and Camden Sports Productions.
