Born in Suriname, he and his family would later move to the Dutch city of Zaandam where he first played football, initially as a goalkeeper, later transitioning to the role of a right winger and finally a forward. He began his senior career with Telstar and AZ Alkmaar before leaving the Netherlands for Portuguese club Campomaiorense in August 1995. He joined Boavista the following year and won the Taça de Portugal with the club in 1997. He was signed by English side Leeds United for a £2 million fee before the 1997–98 season, where he established himself as a prolific goalscorer and went on to win the Premier League Golden Boot award in 1999. He was sold on to Spanish club Atlético Madrid for £10 million the same year, reaching the final of the Copa del Rey despite the club also suffering relegation from La Liga.

Hasselbaink returned to the Premier League with Chelsea for a club record £15 million fee in May 2000, where he once again led the league in scoring during his first season, earning him a second Premier League Golden Boot. He also played in the 2002 FA Cup Final and helped Chelsea to a career-high and then club-record second-place Premier League finish in 2003–04. He moved to Middlesbrough on a free transfer in July 2004 and played in the final of the UEFA Cup in 2006. After being released at the end of the previous season, he signed with Charlton Athletic in July 2006 before joining Cardiff City in August 2007. He played on the losing side in the 2008 FA Cup Final before retiring from play at the end of the season. He also scored nine goals in 23 matches during a four-year international career for the Netherlands national team, appearing at the 1998 FIFA World Cup.

In May 2013, he was appointed manager of Royal Antwerp in the Belgian Second Division, where he stayed for one season. In November 2014, he was hired by Burton Albion in England, and in his first season, he led them to their first-ever promotion to League One as champions of League Two. In December 2015, he was appointed manager of Queens Park Rangers in the Championship. He lasted 11 months in the job until he was dismissed in November 2016.
