Robert Louis Ginepri ( ; born October 7, 1982) is an American tennis coach and a former professional player. He won three ATP singles titles in his career and achieved a career-high ranking of World No. 15 in December 2005. Ginepri's best Grand Slam result was the semifinals of the 2005 US Open.
In August, he reached the semifinals of an ATP Masters Series tournament for the first time in his career, in Cincinnati, Ohio.

His summer hardcourt record was 14–3 when he arrived two weeks later at the 2005 US Open as an unseeded player.

He also won the inaugural Superset Tennis tournament, a groundbreaking one-set, one-day tournament, earning him prize money of $250,000. He reached world No. 15 in the ATP rankings on 26 December 2005, the highest ranking of his career.
Ginepri lost in the third round of both the 2007 Australian Open and the US Open and the first round of both the French Open and Wimbledon. He finished the year 2007 ranked outside the top 100 for the first time since 2002, at world No. 134.

On grass court, Ginepri lost in the second round of The Artois Championships in London to Andy Roddick and the first round of Wimbledon to Gonzalez. On June 23, 2008, Ginepri's ranking was world No. 59, a rise of 112 places since January 28, 2008. In August 2008, Ginepri made his Olympic debut at the 2008 Olympic Games in Beijing, China.
In July 2009, Ginepri made his debut in the World Team Tennis league, playing for the new Washington Kastles team. At the 2009 US Open, Ginepri advanced to the second round, before losing to Nicolás Almagro in five sets.
In October, Ginepri was involved in a biking accident causing him to have surgery on his arm. He didn't return to the pro tour until July 2011.
Ginepri participated in the 2011 Atlanta Tennis Championships as a wildcard. His first match was against fellow wildcard Tommy Haas. He received a wildcard to the US Open, where he defeated Brazilian João Souza in the first round in a four-set match. He then lost to John Isner in the second round.
In 2014, having competed in futures tournaments throughout the start of the season, Ginepri participated in his first Challenger at the 2014 Sarasota Open, retiring after one match in the first round of qualifying. After winning the USTA wildcard entry for the 2014 French Open, he lost to Rafael Nadal in the first round, in straight sets.
On February 22, 2007, Ginepri participated on Spike TV's Pros vs. Joes with Rik Smits, Rob Dibble, and Andre Rison. In 2012, he was briefly linked with actress Minnie Driver.
Ginepri coached the U.S. Davis Cup team starting in February 2018. At the same time he continued to coach Frances Tiafoe, with whom he started working since the fall of 2016, until the end of the 2018 season, but not on a completely full-time basis. He started coaching Marcos Giron in mid-2020 season, during the summer, into the 2021 season.
Ginepri coached Mackenzie McDonald in 2023, JJ Wolf in 2024. He coached Alex Michelsen also in 2024 starting around the US Open until the end of the 2025 season.
