2002 (MMII) was a common year starting on Tuesday of the Gregorian calendar, the 2002nd year of the Common Era (CE) and Anno Domini (AD) designations, the 2nd year of the 3rd millennium and the 21st century, and the 3rd year of the 2000s decade.

The effects of the September 11 attacks of the previous year had a significant impact on the affairs of 2002. The war on terror was a major political focus. Without settled international law, several nations engaged in anti-terror operations, and human rights concerns arose surrounding the treatment of suspected terrorists. Elsewhere, the Colombian conflict and the Nepalese Civil War represented some of the most severe militant conflicts, while the conflict between India and Pakistan was the only one between two sovereign nations. Religious tensions permeated the year, including violence between Hindus and Muslims in India during violent riots and other attacks and attacks on Jews in response to the Second Intifada. The Catholic Church grappled with scrutiny amid sexual abuse cases.

East Timor was established as a new sovereign nation, and the African Union began operating as a new intergovernmental organization. The International Criminal Court was founded in July. The global economy was stagnant as it slowly moved past the early 2000s recession. South America endured an economic crisis, and the telecommunications and information technology industries faced their own economic declines. The Euro was introduced as a new currency at the beginning of the year.

The year 2002 was the second hottest on record at the time. Eruptions of Mount Nyiragongo severely affected surrounding populations in central Africa. The discovery of Quaoar in October challenged the conventional definition of a planet. Small RNA was discovered in 2002, and the human ancestor Sahelanthropus was first described.

Norway won the most gold medals in the 2002 Winter Olympics, which were held in Salt Lake City. The popular film franchises Harry Potter and The Lord of the Rings saw continued success while James Bond and Star Wars were less successful than other franchise instalments. Pop music lost its popularity in 2002 amid the rise of country and hip hop, with hip hop artist Eminem producing the year's most successful album, The Eminem Show.

Conflicts in Afghanistan, Chechnya, Israel, and the Philippines were directly related to countering Islamic terrorism.^[6]: 87

The Colombian conflict escalated after far-left insurgents occupied demilitarized zones and kidnapped Íngrid Betancourt, effectively ending peace talks. The insurgents began bombing cities, and over 200,000 Colombians were displaced by the conflict in 2002.^{[6]: 91–92}

The Nepalese Civil War escalated in 2002, with casualties approximately equaling the combined totals from 1996 to 2001; half of this increase was civilian casualties, as civilians were targeted by both the Nepali government and the communist insurgents.^{[6]: 88–89} Chechen insurgents in Russia escalated their attacks during the Second Chechen War, destroying a Russian Mil Mi-26 in August and causing a hostage crisis in Moscow.^{[6]: 93–94} The Second Liberian Civil War also escalated, causing widespread displacement of civilians.^[7]: 90

The only direct conflict between nations in 2002 was the India–Pakistan standoff in Kashmir,^[5] beginning in late 2001. This conflict was primarily one of brinkmanship, with the threat of nuclear warfare.^[6]: 88 Riots in Gujarat and suicide bombings in Jammu further escalated tensions.^[10]: 87

The Second Intifada continued in 2002 between the Israel Defense Forces and Palestinian paramilitary groups with an escalation in violence. Palestinian suicide bombings became coordinated to maximize the number of civilian casualties, while the Israeli military killed approximately twice as many Palestinians in retaliation.^[10]: 73 In response to the suicide bombings, Israel carried out Operation Defensive Shield in March.^[7]: 413 Under this operation, Israel occupied much of West Bank,^[7]: 413 and it and briefly held Palestinian president Yasser Arafat under house arrest.^[6]: 95 The Battle of Jenin was particularly destructive, with the United Nations finding both parties to be irresponsible regarding collateral damage.^[6]: 96

Economic downturn in the aftermath of the September 11 attacks limited the art industry in 2002. Organizations were less willing to give patronage, and tourists were less willing to visit art exhibitions and museums, particularly in New York and the Middle East.^[9]: 502 The Documenta11 exhibition took place in Kassel, Germany, contributing to the early movement of art globalization with its focus on experimental and documentary works from developing nations.

The 2002 Atlantic hurricane season saw 12 named storms, a near-average number. Most of them were relatively minor, with only 4 four becoming hurricanes, of which two attained major hurricane status. The season's activity was limited to between July and October, a rare occurrence caused partly by El Niño conditions. The two major hurricanes, Hurricane Isidore and Hurricane Lili, both made landfall in Cuba and the United States, and combined were responsible for most of the season's damages and deaths.^[33] The 2002 Pacific typhoon season entailed a typical number of typhoons, but they were above average in intensity with 46% of typhoons reaching "intense strength".
