15 is a triangular number: 1 + 2 + 3 + 4 + 5
15 is the positive solution to: 2x2 - 27x = 45

15 = 42 - 12

15 is the number of 'The Devil' in the major arcana of Tarot cards.

In the Hebrew numeral system, the numbers 15 and 16 are represented as 15 hebraic (9+6) and 16 hebraic (9+7) respectively, instead of 15 hebraic (10+5) and 16 hebraic(10+6). This is done in order to refrain from using the sacred combinations, called tretragrammaton, that are a part of the name of God in Judaism.

The only 15-letter word that can be spelled without repeating a letter is "uncopyrightable".
