Alwalkeria maleriensis est genus dinosauriorium basalium saurischiorum ex Triassico Superiore Indiae. Ea fuit parva omnivorum bipedale.

Hoc reptile a Sankar Chatterjee anno 1987 primum Walkeria maleriensis appellatum est ut decus Alick Walker, notissimi palaeontologistae Britannici, et Formationis Maleri Andhra Pradesh Indiae, ubi fossilia huius dinosaurii inventa sunt; generico autem nomen a quodam bryozoo praeoccupato, novum nomen a Chatterjee et Ben Creisler anno 1994 excogitatum est.

Sua reliquia constant ex (partim) maxilla, mandibula, viginti quattuor vertebris, femore, astragalo, calva quattuor centimetra longa. Aliquibus proprietatibus (e.g., mandibulis), eoraptoris similis est.
