2016 Formula One World Championship

The 2016 FIA Formula One World Championship was the 70th season of the Fédération Internationale de l'Automobile (FIA)'s Formula One motor racing. It featured the 67th Formula One World Championship, a motor racing championship for Formula One cars which is recognised by the sport's governing body, the FIA, as the highest class of competition for open-wheel racing cars. Teams and drivers took part in twenty-one Grands Prix—making for the longest season in the sport's history to that point—starting in Australia on 20 March and finishing in Abu Dhabi on 27 November as they competed for the World Drivers' and World Constructors' championships.

The 2016 season saw the grid expand to twenty-two cars with the addition of the Haas F1 Team entry. Renault returned to the sport as a constructor after a four-year absence following their takeover of Lotus prior to the start of the season. The calendar similarly expanded, with the return of the German Grand Prix. The European Grand Prix was also revived, with the event visiting a new circuit in Azerbaijan's capital city, Baku.

Nico Rosberg won his only World Drivers' Championship title in the final race of the season. With nine wins and seven other podiums, Rosberg beat teammate and defending World Champion Lewis Hamilton by five points. In doing so, Rosberg followed the success of his father in 1982 - becoming the second son of a champion to become champion himself, a feat previously achieved by Damon Hill in 1996 and the third title winner for Mercedes. Rosberg announced his retirement from the sport shortly after winning the title.

In the World Constructors' Championship, Mercedes successfully defended their title for the second consecutive year with a then-record points tally of 765 points, beating Red Bull Racing by 297 points. Ferrari finished third overall, a further seventy points behind.

As of 2026, this is the last championship for a German driver. This was the last season to be held during Bernie Ecclestone's tenure as Chief Executive of the Formula One Group. Ecclestone would be removed from his role on 23 January 2017 after nearly 40 years in the job following Liberty Media's purchase of the sport from CVC Capital Partners. It was the final full season for 2009 World Champion Jenson Button, who would only make one more Grand Prix appearance at the 2017 Monaco Grand Prix. Renault also returned as a full works manufacturer team for the first time in over six years.

The following teams and drivers took part in the 2016 Formula One World Championship. All teams competed with tyres supplied by Pirelli.

Five drivers drove in free practice sessions in place of regular drivers.

Several team changes took place before the season began. Haas F1 Team, a team formed by NASCAR Sprint Cup Series team owner Gene Haas, joined the Formula One grid, becoming the first American team to compete since the unrelated Haas Lola team competed in 1986. The team used power units supplied by Ferrari and a chassis developed by Dallara. Dallara had last participated in Formula One as the chassis manufacturer for HRT in 2010. Renault returned to Formula One as a full factory-supported team after they purchased Lotus from Genii Capital, the venture capital firm they had originally sold the same team to in 2010, and supplied engines to up until the end of 2014. Lotus's participation in the 2016 season was in question pending the resolution of a High Court case brought against the team by HM Revenue and Customs over unpaid PAYE tax.
