The 2010 Rally de Portugal was the 44th Rally de Portugal and the sixth round of the 2010 World Rally Championship season. The rally took place over May 27–30, and was based in Faro, the capital city of the Algarve region. The rally was also the second round of the Junior World Rally Championship and the fifth round of the Super 2000 World Rally Championship.

After losing the lead on the final stage in New Zealand, Citroën Junior Team driver Sébastien Ogier took his first WRC victory by 7.9 seconds ahead of championship leader Sébastien Loeb. Third place went to Loeb's team-mate Dani Sordo, with Mikko Hirvonen edging out Petter Solberg for fourth place on the final run through the super-special stage at the Estádio Algarve. Ogier's victory lifted him into second place in the championship standings, 38 points behind Loeb, after his sixth podium finish out of six rallies in 2010.

The Rally de Portugal (formerly: Rallye de Portugal) is a rally competition held in Portugal. First held in 1967, the seventh running of the race, the 7º TAP Rallye de Portugal was the third event in the inaugural FIA World Rally Championship in 1973. The rally remained on the WRC calendar for the next 29 years, and after being dropped for 2002–2006, the event returned to Portugal in 2007. During the 1970s, 1980s and early 1990s, Rally de Portugal was a mixed event between asphalt and gravel. Currently it is an all-gravel event.

Rally de Portugal has been awarded "The Best Rally in the World" five times and in 2000 "The Most Improved Rally of the Year". The most successful driver in the history of the rally is Finland's Markku Alén, who has won the event five times (1975, 1977, 1978, 1981 and 1987).

The Rally of Portugal has an important aspect which once made it so famous or maybe infamous; crowd control. During the 1970s and especially the 1980s, Portugal was known for spectators standing on the roadway even as the cars drove by, often resulting in near-collisions, and finally in the 1986 season a collision between cars and spectators. It was the last year the Group B cars domininated the WRC scene. And it was because of a tragic accident which occurred during the rally that the future of Group B cars came under scrutiny. The final blow came at the Tour de Corse later that year with the death of Henri Toivonen.

Portugal ⁱ/ˈpɔrtʃʉɡəl/ (Portuguese: Portugal, IPA: [puɾtuˈɣaɫ]), officially the Portuguese Republic (Portuguese: República Portuguesa) is a country situated in southwestern Europe on the Iberian Peninsula . Portugal is the westernmost country of mainland Europe, and is bordered by the Atlantic Ocean to the West and South and by Spain to the North and East. The Atlantic archipelagos of the Azores and Madeira are part of Portugal. The country is named after its second largest city, Porto, whose Latin name was Portus Cale.

The land within the borders of the current Portuguese Republic has been continuously settled since prehistoric times: occupied by Celts like the Gallaeci and the Lusitanians, integrated into the Roman Republic and later settled by Germanic peoples such as the Suebi, Swabians, Vandals and the Visigoths. In the 8th century most of the Iberian Peninsula was conquered by Moorish invaders professing Islam, which were later expelled by the Knights Templar under the Order of Christ. During the Christian Reconquista, Portugal established itself as an independent kingdom from León in 1139, claiming to be the oldest European nation state.

Mikko Hirvonen (born 31 July 1980, Kannonkoski) is a Finnish rally driver currently driving for the Citroën Total World Rally Team in the World Rally Championship. He placed third in the drivers' championship and helped Ford to the manufacturers' title in both 2006 and 2007. In 2008, 2009 and 2011, he finished runner-up to Sébastien Loeb.

Hirvonen then campaigned a two-year-old Ford Focus RS WRC 03 and led one rally during the course of the year, and scored a career-best third place finish at the Rally Catalunya as a privateer.
