What is Challenge Rating (CR) in D&D 5e?

A monster's Challenge Rating is a quick estimate of how deadly it is to a party of four adventurers of a level roughly equal to that CR. Defeating it grants the listed XP, and its CR sets the proficiency bonus used for its attack rolls, save DCs, and skill checks. CR runs from 0 (harmless) through 1/8, 1/4, and 1/2 up to 30 (world-ending).
