Earth-16 or Universe-16 is the universe in which Young Justice takes place. It is part of DC Comics' multiverse of 52 parallel worlds that arose after the Infinite Crisis.

Greg Weisman and Brandon Vietti asked DC for one of the Earths that had not been used, and were assigned Earth-16.

However, Earth-16 had been used before. In a DC Nation column, it was said to be the home of the "Super-Sons", and in the Countdown: Arenaminiseries, a Superman of Earth-16 named Christopher Kent appeared. When this was discovered, it was too late to change it for Young Justice, but those events have thus far been ignored.

The timeline lists the events that happened on Earth-16 in chronological order.
