勞動節通常是年度性的節日，目的是為了慶祝工人對社會和經濟的所作的貢獻。勞動節是十九世紀以來工人運動的產物。
世界上大多數國家的勞動節是在5月1日。因而，通常也稱之為國際勞動節。美國和加拿大的勞動節是在9月的第一個星期一。紐西蘭的勞動節是十月的第4個星期一。澳大利亞不同的地區對勞動節有不同的規定。日本類似的節日稱為勤勞感謝之日（きんろうかんしゃのひ），在11月23日。

A Labour Day is an annual holiday celebrated all over the world that resulted from efforts of the labour union movement, to celebrate the economic and social achievements of workers.
The celebration of Labour Day has its origins in the eight hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest. On 21 April 1856 Stonemasons and building workers on building sites around Melbourne, Australia, stopped work and marched from the University of Melbourne to Parliament House to achieve an eight hour day. Their direct action protest was a success, and they are noted as the first organized workers in the world to achieve an eight hour day with no loss of pay, which subsequently inspired the celebration of Labour Day and May Day.
