O dos **laurasiaterios** (*Laurasiatheria*) é un hipotético clado de mamíferos placentarios co rango de cohorte ou superorde, segundo os autores. Está formado por sete ordes con especies actualmente viventes, e seis ordes extintas.

## Etimoloxía

O latín científico *Laurasiatheria* fórmase cos elementos Laurasia-, formado a partir de *Lau-* (de Laurentia, antigo continente que na actualidade forma parte do cratón de Norteamérica), *Asia*, e -theria, forma latina plural do grego θηρίον *thēríon*, "besta salvaxe". Polo tanto o seu significado é "as bestas de Laurasia" (isto é, os animais de Eurasia e Norteamérica).

## Ordes

Hoxe en día recoñécense as seguintes ordes con representantes vivos:

* *Erinaceomorpha*
* *Soricomorpha*
* *Chiroptera*
* *Cetartiodactyla* (*Cetacea + Artiodactyla)*
* *Perissodactyla*
* *Pholidota*
* *Carnivora*

Ademais, estas outras ordes extintas se asignaron á superorde:

* *Meridiungulata*
* *Condylarthra*
* *Dinocerata*
* *Mesonychia*
* *Cimolesta*
* *Creodonta*
