'''델타 IV'''는 미국의 우주로켓이다. [[미국 국방부]]의 [[EELV]] 계획의 하나로 보잉에서 개발되었다. 민간용과 군용 겸용이다.

최종적으로 발사장에서 [[ULA]]에 의해 조립된다.<ref>{{웹 인용 |url=http://www.comspacewatch.com/news/viewpr.html?pid=21394 |제목=United Launch Alliance Transaction completed |확인날짜=2008년 6월 30일 |보존url=https://web.archive.org/web/20080222085830/http://www.comspacewatch.com/news/viewpr.html?pid=21394 |보존날짜=2008년 2월 22일 |url-status=dead }}</ref>

보잉의 델타 IV는 경쟁자인 록히드 마틴의 [[아틀라스 V]]와 같이, [[반덴버그 공군 기지]] 또는 [[케이프커내버럴 공군 기지]]에서 발사된다. 아틀라스 V가 13톤 운반능력인데 비해, 델타 IV는 22톤으로, 20톤인 우주정거장 모듈을 올릴 수 있다. 고비용 비판으로 퇴역한 [[우주왕복선]]은 24톤 운반능력이었다.
