Yes and no. In the comics and all animated versions, he has no biological siblings. In the 배트맨 Forever Movie he had a brother added, Mitchell Grayson.
He was however adopted 의해 Bruce, as was Tim Drake, so along with Damian Wayne and possibly Terry McGinnis, Richard Grayson may have 3 brothers as Bruce's son.

Side note, in an episode of Teen Titans GO, Beast Boy did depict a diagram with a SD Bald pacifier sucking baby listed as Dick's long 로스트 brother... which is as close as anything besides 배트맨 Forever comes to acknowledging a 4th Flying Grayson
