Rio Haryanto (born 22 January 1993) is an Indonesian former racing driver and businessman, who competed in Formula One at 12 Grands Prix in 2016.

Born and raised in Surakarta, Central Java, Haryanto began his career in karting, winning multiple continental championships before progressing to junior formulae in 2008.

He was most competitive in the FAsia 2.0 series, winning two races to finish third overall in the championship behind expatriate European drivers Felix Rosenqvist and Matthias Beche.

This included a perfect run of four outright victories, pole positions and fastest laps in the four consecutive races held at his home circuit of Sentul.

Despite increasing his victory count to two, with wins at the Nürburgring and the Hungaroring, his inconsistency—including a run of seven races without scoring points at the start of the year—saw him slip to seventh place in the championship, behind Quaife-Hobbs.

[2][3][4] In addition to his GP3 duties, Haryanto also drove for the DAMS team in the Auto GP series, competing in all but one round of the championship as it clashed with the GP3 schedule.

Driving alongside Sergey Afanasyev and part-timer Tambay, he took a win at the Circuit Ricardo Tormo in Valencia and finished seventh in the drivers' standings.

In the autumn of that year, he won the right to test with Virgin at the end of the 2010 season due to his finishing position as the highest ranked Manor driver in the GP3 final standings.

Haryanto and 2012 GP2 Series teammate Max Chilton drove for Marussia in the first young driver tests of 2012, held in-season at Silverstone.

[15] Running over the course of two days, Haryanto completed three hundred kilometres of testing, satisfying one of the conditions to be eligible for a superlicence and becoming the first Indonesian driver to qualify for one.

[16] On 18 February 2016, Haryanto was confirmed as a driver of Manor Racing for the 2016 Formula One season alongside 2015 DTM Champion Pascal Wehrlein.

[17] He made his debut at the 2016 Australian Grand Prix, however got off to a rocky start with an incident involving Romain Grosjean when they collided in the pit lane during practice.

[23] However, this meant a grid place of 20th due to Renault's Kevin Magnussen having to start from the pitlane after failing to stop for weighing during practice.

He managed to beat the other Renault driver Jolyon Palmer to 21st in China, before he became tangled up in a first-lap crash in Russia that involved Nico Hülkenberg and Esteban Gutiérrez.

Haryanto repeated his Bahrain performance in Spain, with his next race in Monaco bringing him a career-best 15th, albeit 4 laps down and once again the last classified finisher.

He spun off in the wet in Britain, whilst what would turn out to be his final two races again saw him the last classified finisher as his future became unclear due to a lack of sponsorship.
