'''Varanidae''' adalah [[
''Varanus'' mencakup [[komodo]] (kadal terbesar yang masih hidup), [[biawak Papua]], [[biawak sabana]], [[goanna]] dari [[Australia]] dan [[Asia Tenggara]] serta lainnya dengan penampilan khas yang serupa. Kerabat terdekat mereka yang masih hidup adalah [[Anguidae|anguid]] dan [[Heloderma|kadal helodermatid]].<ref name="Fry2006">{{cite journal |last1=Fry |first1=B.G. |last2=Vidal |first2=N |last3=Norman |first3=J.A. |last4=Vonk |first4=F.J. |last5=Scheib |first5=H. |last6=Ramjan |first6=S.F.R |last7=Kuruppu |first7=S. |last8=Fung |first8=K. |last9=Hedges |first9=B. |last10=Richardson |first10=M.K. |last11=Hodgson |first111=W.C. |last12=Ignjatovic |first12=V. |last13=Summerhays |first13=R. |last14=Kochva |first14=E. |date=February 2006 |title=Early evolution of the venom system in lizards and snakes |journal=Nature |doi=10.1038/nature04328 |pmid=16292255 |volume=439 |issue=7076 |pages=584–588|s2cid=4386245 }}</ref>
==Taksonomi==
Varanidae didefinisikan (menggunakan karakteristik morfologi) oleh Estes, de Queiroz dan Gauthier (1988) sebagai klad yang mengandung nenek moyang terbaru dari ''[[Biawak tanpa telinga|Lanthanotus]]'' dan ''Varanus'' dan semua keturunannya.<ref name="estes1998">{{cite book |editor1-last=Estes |editor1-first=Richard J. |editor2-last=Pregill |editor2-first=Gregory K. |last1=de Queiroz |first1=Kevin |last2=Gauthier |first2=Jacques |date=1988 |title=Phylogenetic Relationships of the Lizard Families: Essays Commemorating Charles L.

Lee (1997) menciptakan definisi yang berbeda dari Varanidae, mendefinisikan mereka sebagai klad yang mengandung ''Varanus'' dan semua taksa yang lebih dekat hubungannya dengan ''Varanus'' daripada ''Lanthanotus'';<ref name=LeeMSY>{{cite journal |last=Lee |first=Michael S.
