'''사프라닌'''({{llang|en|safranin}})은 [[조직학]] 및 [[세포학]]에서 사용되는 [[염색 (생물학)|염색]] [[시약]]이다. '''사프라닌 O'''({{llang|en|safranin O}}) 또는 '''염기성 레드 2'''({{llang|en|basic red 2}})라고도 한다. 사프라닌은 일부 염색 과정에서 [[대비염색]]제로 사용되어 [[세포핵]]을 빨간색으로 착색시킨다. 사프라닌은 [[그람 염색]]과 [[내생포자 염색]] 모두에서 고전적인 대비염색제이다. 사프라닌은 또한 [[연골]],<ref>{{저널 인용| author = Rosenberg L | title = Chemical Basis for the Histological Use of Safranin O in the Study of Articular Cartilage | journal = J Bone Joint Surg Am | volume = 53 | issue = 1 | pages = 69–82 | year = 1971 | pmid = 4250366 | doi =  10.2106/00004623-197153010-00007| url = http://www.ejbjs.org/cgi/content/abstract/53/1/69 | format = abstract | url-status = dead | archive-url = https://web.archive.org/web/20080417005221/http://www.ejbjs.org/cgi/content/abstract/53/1/69 | archive-date = 2008-04-17 }}</ref> [[점액]], [[비만 세포]] [[과립]]의 검출에서도 사용할 수 있다.
