Nainggolan was born in Antwerp, the son of Lizy Bogaerts, a Belgian of Flemish ethnicity who raised him with his three half brothers and his twin sister, and Marianus Nainggolan, an Indonesian of Batak background member of the Batak Christian Protestant Church who left them with nothing when he was just a child.
Nainggolan's mother died in 2010, and after her death he tattooed two large wings on his back with her dates of birth and death. He was raised Roman Catholic and speaks Dutch, English and Italian fluently, as well as understanding French.
Nainggolan arrived at Piacenza Calcio in late 2005 at the age of 17, from local K.F.C. Germinal Beerschot. Still a junior he managed to appear in two Serie B games for the club, over the course of two separate seasons.
Nainggolan played 38 matches in the 2008–09 campaign for the Emilia-Romagna side, scoring three goals for an eventual 10th-place finish. On 27 January 2010 he was loaned to Cagliari Calcio in Serie A, with the Sardinians having an option to buy the player permanently at the end of the season. He made his league debut on 7 February, playing seven minutes in a 0–3 away loss against Inter Milan.
However, on 7 January of the following year, Nainggolan was loaned to fellow league team A.S. Roma until the end of the campaign for a fee of €3 million, with an option to make the deal permanent in the ensuing summer for €6 million.
Nainggolan made his debut for his new club on 9 January 2014, starting in a 1–0 home win over U.C. Sampdoria for the season's Coppa Italia which qualified to the quarter-finals. In the same competition, he also helped dispose of Juventus F.C. in said stage by playing the full 90 minutes 12 days later.
On 22 February 2014 Nainggolan scored his first goal for the capital side, grabbing the 1–0 winner against Bologna FC 1909. His second, which arrived on 19 April against ACF Fiorentina (same result) ensured his team automatic qualification to the UEFA Champions League.
Nainggolan signed a permanent deal with Roma in the 2014 summer.
Nainggolan earned his first cap for Belgium on 29 May 2009, against Chile in the Kirin Cup. On 5 March 2014 he scored his first goal for the Red Devils, in a 2–2 friendly draw with Côte d'Ivoire.
