Xandarella is an extinct genus of Xandarellid artiopodan known from the Cambrian of China and Morocco, the type species was described in 1991 from the Chengjiang Biota in China.
An additional species Xandarella mauretanica was described from the Cambrian Stage 5 Tatelt Formation in Morocco in 2017, which only preseved the ventral anatomy.
Like other Xandarellids, the exoskeleton is unmineralised.
The cephalon has pronounced eye slits, presumably derived from ancestral ventral stalked eyes.
