Yom Kippur (/ ˌ j ɒ m k ɪ ˈ p ʊər, ˌ j ɔː m ˈ k ɪ p ər, ˌ j oʊ m -/ YAHM kip- OOR, YAWM KIP -ər, YOHM -; Hebrew: יוֹם כִּפּוּר Yōm Kīppūr, lit. ' Day of Atonement ') is the holiest day of the year in Judaism. It occurs annually on the 10th of Tishrei, corresponding to a date in late September or early October.

For traditional Jewish people, it is primarily centered on atonement and repentance. The day's main observances consist of full fasting and asceticism, both accompanied by extended prayer services (usually at synagogue) and sin confessions. Many Jewish denominations, such as Reconstructionist Judaism (vs. Reform, Conservative, Orthodox, etc.), focus less on sins and more on one’s goals and accomplishments and setting yearly intentions.

Alongside the related holiday of Rosh HaShanah, Yom Kippur is one of the two components of the High Holy Days of Judaism. It is also the last of the Ten Days of Repentance.
