Osaze Tafari De Rosario ( ; born 19 July 2001) is a professional footballer who plays as a striker for Danish Superliga club Sønderjyske, on loan from Major League Soccer club Seattle Sounders FC. Born in the United States and the son of former Canada national team player Dwayne De Rosario, he plays for the Guyana national team.
Early life De Rosario was born in San Jose, California, where his father, Canada national team player Dwayne De Rosario, was playing for the San Jose Earthquakes.
De Rosario is a product of the Toronto FC and New York City FC academies. He spent the 2020 preseason with the NYCFC first-team, appearing in four matches, scoring twice, including a goal against Brazilian club Palmeiras. He departed NYCFC after 2020, and in early 2021 went on trial with Spanish clubs UD San Sebastián de los Reyes and CD Lugo.
Club career In 2018, he played with Toronto FC III in the Canadian third-tier League1 Ontario, making his debut on August 19 against Ottawa South United.
In September 2021, after a successful trial, De Rosario signed a three-year contract with Ukrainian Premier League club Rukh Lviv, and was assigned to the reserves. He made his professional debut for Rukh in the UPL as a starter against Mynai the next month on October 24. In February 2022, he left the club by mutual consent, nine days before the 2022 Russian invasion of Ukraine after United States President Joe Biden urged all American citizens to leave Ukraine.
After leaving Ukraine, De Rosario joined Canadian Premier League club York United on trial during their pre-season in March 2022. The next month on April 6, York announced they had signed De Rosario to a one-year contract, with options for 2023 and 2024. He made his debut in York's season opener against the HFX Wanderers on April 7.

In September, he became the club's all-time leading scorer, when he scored his 12th goal. At the end of the season, he was nominated for the CPL U21 Player of the Year Award, which was ultimately won by Sean Rea. In November 2022, he signed a two-year extension with the club. In August 2023, De Rosario was disqualified from official competitions for one month by the Canadian Centre for Ethics in Sport, after he had tested positive for THC in an in-competition urine test; in an official statement, the player confirmed he would abide by the sanction, while stating his ingestion of THC was accidental. On October 7, he scored a brace in a 2–1 league victory over Vancouver FC, which allowed York United to qualify for the play-offs. At the time of his departure from the club after the 2023, he was the club's all-time leading goalscorer with 19 goals.
In March 2024, he moved to the Tacoma Defiance in MLS Next Pro. He scored his first goal on March 31 against LA Galaxy II. On May 9, 2024, he joined the Seattle Sounders FC first team on a short-term loan, making his debut in a 2024 US Open Cup match against Louisville City FC. He signed another short-term loan later that month as well. He earned MLS Next Pro Player of the Month honours for April 2025. On May 3, 2025, after signing another short-term loan, he made his Major League Soccer debut for the Sounders against St. Louis City SC. On 8 May 2025, Rosario signed a first team contract with the Sounders, joining for the remainder of the 2025 MLS season, with club options for an additional two years.
On 1 September 2026, De Rosario joined Danish Superliga side Sønderjyske on a one-year loan deal.
International career De Rosario was eligible to represent the United States (his country of birth), Canada (through his parents) and Guyana (through his paternal grandparents).
In November 2023, De Rosario accepted a call-up to the Guyana senior national team ahead of their CONCACAF Nations League B matches against the Bahamas and Antigua and Barbuda. He made his debut and scored his first international goal for the Golden Jaguars on November 21, in a 6–0 win over Antigua and Barbuda. In November 2024, he participated in a training camp with the Canada senior team as his father was serving as an assistant, before then re-joining the Guyana team for their CONCACAF Nations League matches. On November 19, he scored a hat trick for Guyana in a 5–3 victory over Barbados in the CONCACAF Nations League.
