1945 (MCMXLV) was a common year starting on Monday of the Gregorian calendar, the 1945th year of the Common Era (CE) and Anno Domini (AD) designations, the 945th year of the 2nd millennium, the 45th year of the 20th century, and the 6th year of the 1940s decade.

A turning point in human history, 1945 marked the end of World War II, ending with the defeat and occupation of Nazi Germany (including Austria) and the Empire of Japan (especially Korea) by the United States and the Soviet Union in the world of two superpowers which has led the beginning of the Cold War (1945–1991). It is also the year the Nazi concentration camps were liberated and the only year in which atomic weapons have been used in warfare.
