Paezan (also Páesan, Paezano, Interandine) may be any of several hypothetical or obsolete language-family proposals of Colombia and Ecuador named after the Paez language.

Currently, Páez (Nasa Yuwe) is best considered either a language isolate or the only surviving member of an otherwise extinct language family (Adelaar & Muysken 2004, Gordon 2005, Matteson 1972, Fabre 2005). It has often been grouped with other languages in a Paezan family, but several of these proposals are based on a historical error. Even before the discovery of the error, Campbell (1997: 173) stated, "There is no consensus upon Paezan, and opinions vary greatly".

One of the most often repeated statements (e.g. Loukota 1968; Kaufman 1990, 1994) is the supposed connection between Páez and the extinct Panzaleo (also known as Pansaleo, Latacunga, or Quito), formerly spoken in highlands of Ecuador. However, Panzaleo is poorly documented and the evidence for this relationship is weak and may be from language contact. Thus, Panzaleo may best be considered an unclassified isolate (Adelaar & Muysken 2004: 393-397; Campbell 1997).

The Andaquí isolate (also extinct) is often connected with Páez in a Paezan grouping. Documentation is a 20-page list of words and expressions by an anonymous author published in 1928 and another word list collected in 1854 by a priest (Manuel María Albis). There are a number of similarities in vocabulary between Andaquí and Páez, as noted by Jolkesky (2015)^[1] and others. In other aspects, the differences are greater.

Jolkesky (2015) also found lexical similarities with Tinigua.^[1]

The Coconucan languages were first grouped together with Páez by Henri Beuchat & Paul Rivet in 1910 (under a larger Chibchan family, which is considerably more inclusive than the conservative Chibchan recognized today). Curnow (1998) shows this is based on misinterpretation of a Moguex vocabulary of Douay (1888), which is a mix of Páez and Guambiano/Totoró. The error has led to subsequent classifiers (e.g. Kaufman 1990, 1994; Campbell 1997; Greenberg 1956, 1987; Tovar & Larruceau de Tovar 1984) to group Páez with Guambiano, missing the obvious identification of Coconucan as Barbacoan.

Matteson's 1972 comparison of Páez and Guambiano vocabularies show just a 5.2% overlap, less than comparisons between Páez and Arawak, Quechua and Proto-Chibchan (respectively 17%, 12%, and 14%). Following linguists such as Matteson (1972), Curnow (1998), Curnow & Liddicoat (1998), and Adelaar & Muysken (2004), the Coconucan languages are now placed under Barbacoan. The question of connections between Páez, Panzaleo, and Andaquí remains open.

Prior to Curnow's correction, the Paez–Coconucan "family" had been connected to various other families. Greenberg included Paezan in a Macro-Chibchan (or Chibchan–Paezan) stock with Barbacoan, Chibchan, Chocoan, Jirajaran, and the isolates Betoi, Kamsá (Sibundoy), Yaruro, Esmeraldeño, Mochica, Cunza (Atacameño), Itonama, and Yurumanguí. Morris Swadesh's Paezan included Páez, Barbacoan, Coconucan, Andaquí, Cunza, Kapixana, and Mashubí. Kaufman's (1990, 1994) Macro-Páesan "cluster" proposal included "Paesan" (as explained above)–Barbacoan, Cunza–Kapixana, Betoi, Itonama, and Warao.
