Pioli, a native of Parma, started his own playing career for his home city team, Parma. Successively, he was signed by Juventus, with whom he made his Serie A debut in 1984, winning the league title, the European Cup, the European Super Cup and the Intercontinental Cup during his three seasons with the club. After being sold to Hellas Verona in 1987, Pioli moved to Fiorentina in 1989, where he spent six years of his career, before spending two seasons with Padova. After successive season-long spells in Serie C with Pistoiese and Fiorenzuola, he ended his career in 1999 with Colorno of Eccellenza Emilia-Romagna (the sixth-highest level of Italian at that time; the top level of the Emilia-Romagna regional league system), playing alongside his brother Leonardo.
From 1999 to 2002 Pioli coached Bologna's youth team (winning a championship with Allievi Nazionali's team), and Chievo's in 2002–03. In 2003–04, he was appointed as head coach of Serie B club Salernitana. He moved to Modena, still of Serie B, in 2004.
In 2006, Pioli was named as Parma's head coach, therefore returning to his home city and marking his Serie A debut as a manager. However, he was sacked on 12 February 2007 after a 3–0 loss to Roma which brought Parma down to second-last place and replaced by Claudio Ranieri.
On 11 September 2007, Piolo was unveiled as new head coach of Serie B club Grosseto, replacing Giorgio Roselli, who was sacked after three consecutive defeats in the first three league matches, and managed to lead the Tuscan minnows to an impressive mid-table finish in their first season in the Serie B. He then served as head coach of Piacenza for their 2008–09 Serie B campaign. In July 2009, he left Piacenza to join Sassuolo as new head coach of the neroverdi.
On 10 June 2010, Pioli was named head coach of Serie A club Chievo on a 12-month contract.
On 4 October 2011, Piolo was named new head coach of Bologna in Serie A, replacing the sacked Pierpaolo Bisoli. After two troublesome seasons with Bologna, both ended with the team struggling in the bottom half of the Serie A table but always escaping relegation, he was removed from his managerial duties on 8 January 2014, with Davide Ballardini appointed as his replacement.
On 12 June 2014, it was confirmed Pioli's appointment as new head coach of Lazio in place of Edoardo Reja. In his first season at the club, he led Lazio to a third-place Serie A finish. On 11 June 2015, he was offered a new 2+1-year contract.
On 8 November 2016, Pioli was appointed as the new head coach of Internazionale on an 18-month contract. On 20 November, Inter drew 2-2 against Milan in a Serie A Derby della Madonnina match, Pioli's first competitive match as head coach of the club. He was sacked on 9 May 2017. Inter had won 12 of the first 16 Serie A matches that Pioli was in charge of (draw with Milan, losses to Napoli, Juventus and Roma), but this was followed by two draws and five losses in their last seven Serie A matches prior to his sacking. 
On 6 June 2017, Pioli was named new head coach of Fiorentina. He signed for two years with another optional year.
