Negroid (also known as Congoid) is a grouping of human beings historically regarded as a biological taxon.
 The term has been used by forensic and physical anthropologists to refer to individuals and populations that share certain morphological and skeletal traits that are frequent among populations in most of Sub-Saharan Africa and isolated parts of Southeast Asia (Negritos).
 First introduced in early racial science and anthropometry, "Negroid" denoted one of the three purported major races of humankind (alongside Caucasoid and Mongoloid).
 Many social scientists have argued that such analyses are rooted in sociopolitical and historical processes rather than in empirical observation.
 However, "Negroid" as a biological classification remains in use in forensic anthropology.
In Brazil, a sarará (] or ] ) is a multiracial person, being a particular kind of "mulato" or "juçara" (a tri-racial pardo with Amerindian features), with perceivable Negroid facial features, light complexion and fair but curly hair, called "cabelo crespo", or fair but Afro-like frizzly hair, called "carapinha", "cabelo encarapinhado" or "cabelo pixaim" (] ).
 In the 1998 IBGE PME (Monthly Employment Survey), 0.04% of respondents identified, in an inquiry on race/colour, as "sarará".
