GARGOYLES MEETS THE SPIDER-MAN MEETS YOUNG JUSTICE are a series of non-canonical crossover Radio Plays written by Greg Weisman for both The Gathering of the Gargoyles and CONvergence conventions.
The first non-canonical crossover ("Religious Studies 101: A Handful of Thorns"), however, predates Young Justice and was simply referred to as THE SPECTACULAR SPIDER-MAN MEETS GARGOYLES. 
References and characters from other projects Greg Weisman has worked on, such as W.I.T.C.H. and Star Wars Rebels, have also had cameos in the Radio Plays.
