There are 39 creatures with a challenge rating of 15 in our open-licensed bestiary, drawn from 8 source books. Each is worth 13,000 XP and has a proficiency bonus of +5. As a rule of thumb, one CR 15 monster is a fair fight for four rested level-15 characters; for bigger battles, give it lower-CR minions.

Monstrosities are the most common (8), followed by dragons (7) and aberrations (5). Armor Class runs from 15 to 19 (typically 18) and hit points from 97 to 275 (typically 212).
