He began his career with Ligue 2 side Amiens, impressing enough to earn a move to Premier League side Blackburn Rovers in 2009 for £650,000. He spent three years at Ewood Park which ended with Rovers being relegated at the end of the 2011–12 season. He remained in the Premier League however, joining Stoke City for £3 million. At Stoke, Nzonzi established himself as a key member of the squad under Tony Pulis and then under Mark Hughes, where his performances during the 2014–15 earned him the Player of the Year award.

Nzonzi represented France at under-21 level. He turned down the chance to represent his ancestral DR Congo at senior international level, and was unsuccessful in his attempt to become eligible to play for England. In November 2017, he made his debut for the senior France squad, and he was part of their team that won the 2018 FIFA World Cup.
