Serge Jonás Ibaka Ngobila[a][1] (/ˈsɜːrdʒ iːˈbækə/;[2] born 18 September 1989)[3][4] is a Spanish-Congolese professional basketball player for Real Madrid of the Spanish Liga ACB and the EuroLeague.

Ibaka started playing basketball at a very young age with his first club, Avenir du Rail, using the sport as an escape from his mother's untimely death and his father's imprisonment during the Second Congo War.

[7] His father organized for the family to flee the country prior to the war, but ended up as a political prisoner upon their return.

[11] In 2008, Ibaka entered several international showcases, picking up an MVP award at the Reebok Eurocamp[6] and the attention of NBA scouts.

He then signed a three-year contract with Ricoh Manresa from the ACB League in Spain, keeping the option to leave for the NBA after each season.

In July 2009, the Thunder paid the buyout for Ibaka's deal with Manresa and signed him to a two-year contract with two more optional seasons.

On 19 February 2012, he recorded his first career triple-double against the Denver Nuggets, scoring 14 points, grabbing 15 rebounds and getting a career-high 11 blocks.

In the Finals, Ibaka averaged 7.0 points and 5.0 rebounds, but the Thunder fell to the Miami Heat in five games.

In 2013–14, Ibaka averaged career highs of 15.1 points and 8.8 rebounds per game, and led the league in total blocks (219) for the fourth straight season.

In a series-clinching win over the Los Angeles Clippers in the conference semifinals, Ibaka suffered a left calf injury that was expected to sideline him for the remainder of the 2014 playoffs.

The Thunder eventually fell to the Spurs in six games as Ibaka averaged 12.2 points, 7.3 rebounds and 2.4 blocks throughout the playoffs.

[21] On 17 March, he was ruled out for four to six weeks after undergoing arthroscopic surgery to address right knee soreness.

[24] He made his debut for the Magic in their season opener on 26 October, recording 14 points and seven rebounds in a 108–96 loss to the Miami Heat.

[25] On 13 November, Ibaka scored a career-high 31 points and hit a game-winning baseline jumper to lead the Magic to a 119–117 victory over his former team, the Oklahoma City Thunder.

[33] On 4 November 2018, Ibaka made his first 14 shots on the way to a career-high 34 points in a 121–107 win over the Los Angeles Lakers.

[34] On 3 February 2019, Ibaka had 16 points and 12 rebounds in a 121–103 victory over the Los Angeles Clippers, marking a career-best sixth straight double-double, Toronto's longest streak since Chris Bosh had eight in November 2009.

[45] On 16 September 2023, Ibaka officially signed with Bayern Munich of the German Basketball Bundesliga (BBL) and the EuroLeague.

[54] Having experienced hunger and poverty during his childhood, he has also sponsored drop-in meal programs in Toronto through his Serge Ibaka Foundation.

[59] Ranie's mother conveyed the news to Desire, Ibaka's father, who chose to keep it a secret.

[61] On 3 April 2017, Ibaka was announced as the newest member elected to the board of directors of the National Basketball Players Association (NBPA) Foundation, the charitable arm of the NBPA which provides strategic funding and support for players' community engagement initiatives worldwide.
