His most serious conviction is second-degree murder, which carries a maximum prison sentence of 40 years in Minnesota.
Chauvin was led away from the courtroom in handcuffs and will remain in Police custody until he is sentenced in June.
The jury came to the unanimous decision after hearing a wide range of testimony from witnesses presented by both the defense and prosecution during the three-week trial, but only needed about 10 hours of deliberation to reach a verdict.
Although he had the option to tell the jury his side of the story, Chauvin declined to testify, after invoking the 5th Amendment in court in Minneapolis.
On 25 May 2020, Chauvin knelt on Mr Floyd’s neck for more than nine minutes while detaining him face-first against the pavement in handcuffs during an arrest for using a counterfeit $20 bill.
The murder set off a global wave of protests against police brutality.
Mr Floyd pleaded for air and told officers he couldn’t breathe 27 times, as three officers held him down until he lost consciousness and didn’t have a pulse. They only removed themselves minutes later once paramedics arrived and lifted Mr Floyd’s limp body onto a stretcher.
Chauvin is believed to be only the second on-duty Minneapolis Police officer in the department’s more than 150-year history to be convicted of murder, and the first white officer.
During closing arguments on Monday 19 April, prosecutor Steve Schleicher said that Chauvin ignored his Police training and, as a result, killed Mr Floyd.
“The defendant abandoned his values, abandoned his training, and killed a man,” Mr Schleicher said.
“This was not an accident,” he continued. “He did what he did on purpose, and it killed George Floyd. That force for 9 min and 29 seconds, that killed George Floyd. And he betrayed the badge and everything it stood for.”
