感恩节（英语：Thanksgiving Day，法语：Jour de l'Action de grâce），是美国和加拿大的全国节日，为感谢上天赐予一年度丰收的祝福。美国感恩节定于每年11月第四个星期四。

1620年，五月花号船满载英国受迫害的清教徒到达美洲。当年冬天，不少人饥寒交迫，染病身亡。在印第安人帮助下，新移民学会了狩猎、种植玉米、南瓜，并在来年迎来了丰收。他们邀请印第安人庆祝节日，感谢其帮助。 有 在美国，自1941年起，感恩节定于每年11月的第四个星期四，并从这一天起休假两天，这一天通常被认为标志着圣诞采购季节的正式开始。加拿大的感恩节则起始于1879年，定于每年10月第二个星期一，与美国的哥伦布日相同。联合国总部于感恩节当天放假。

Thanksgiving Day is a national holiday celebrated in Canada and the United States. It was originally celebrated as a day of giving thanks for the blessing of the harvest and of the preceding year. Thanksgiving is celebrated on the second Monday of October in Canada and on the fourth Thursday of November in the United States. Several other places around the world observe similar celebrations. Although Thanksgiving has historical roots in religious and cultural traditions, it has long been celebrated in a secular manner as well.
