Henningsmoenicaris is an extinct genus of Cambrian arthropods from the Orsten of Sweden.

The genus contains a single species, Henningsmoenicaris scutula, with the specific name, scutula referencing the large, bowl-shaped carapace.

[2] Henningsmoenicaris unusually had an almost 360° field of vision, with two extremely long stalked eyes facing in almost all directions at once, even inwards to give depth perception to the opposite eye.

[3] Aside from this, it is a relatively "ordinary" Orsten arthropod with a large bowl-shaped head shield, five pairs of differentiated head appendages including antennules used for swimming, a three-segmented thorax with a pair of appendages on each segment (alongside a ninth pair seemingly still developing in the most developed complete specimen), a five-spined tail segment and a hypostome on the head.

The most developed complete fossil is roughly 550 micrometers long, however a trunk fragment of a much larger and more developed specimen suggests even this form is a larva.
