Lacertilia was named by Owen (1842). It is extant. It was considered monophyletic by Prothero and Estes (1980).

It was reranked as the suborder Lacertae by Gadow (1898); it was synonymized subjectively with Sauria by Hay (1902), Kuhn (1966) and Dundee (1989); it was corrected as Lacerti by Jaekel (1910); it was synonymized subjectively with Sauria by Sulimski (1975) and Lingham-Soliar (1994); it was reranked as the unranked clade Lacertilia by Sullivan (1986), Nicholls and Meckert (2002) and Augé and Rage (2006); it was reranked as the suborder Lacertilia by Zittel (1890), Woodward (1898), Osborn (1903), Lambe (1908), Swinton (1934), Roxo (1937), Kuhn (1946), Huene (1954), Miller (1967), Seiffert (1975), Carroll and Galton (1977), Prothero and Estes (1980), Thurmond and Jones (1981), Carroll (1982), Estes (1983), Stritzke (1983), Carroll (1988), Gao and Fox (1991), Gao and Fox (1996), Frank and Ramus (1996), Gao and Hou (1996), Peng et al. (2001), Venczel and Stiuca (2008) and Böhme (2010).

It was assigned to Lepidosauria by Zittel (1890); to Autosauri by Gadow (1898); to Squamata by Osborn (1903) and Osborn (1904); to Lyognatha by Jaekel (1910); to Squamata by Miller (1967); to Sauria by Estes (1983); to Sauria by Sullivan (1986); to Squamata by Nicholls and Meckert (2002); to Reptilia by Owen (1861), Cope (1871), Leidy (1873), Cope (1875), Günther (1886) and Augé and Rage (2006); and to Squamata by Woodward (1898), Osborn (1903), Lambe (1908), Swinton (1934), Roxo (1937), Kuhn (1946), Huene (1954), Seiffert (1975), Carroll and Galton (1977), Prothero and Estes (1980), Thurmond and Jones (1981), Carroll (1982), Stritzke (1983), Carroll (1988), Gao and Fox (1991), Gao and Fox (1996), Frank and Ramus (1996), Gao and Hou (1996), Peng et al.
