Denis Vieru (born 10 March 1996) is a Moldovan judoka who competes in the men's half-lightweight (66 kg) category. He competed in the men's 66 kg event at the 2020 Summer Olympics in Tokyo, Japan, without winning a medal,[1] but he won a bronze medal in the same event at the 2024 Summer Olympics in Paris, France.
Vieru's medal as well as his points from the 2019 summer's competitions were suspended for a while, while the Moldovan was investigated for use of doping.[7] However, Vieru and his advocates were able to prove that there was "neither will to doping, nor negligence" on the athlete's part, which meant that Vieru only received a three month suspension instead of the regular two years, and was able to keep his medal and his world ranking points. The documents about the events have been sealed from the public.[8]
