Harrimanella is a genus of flowering plant in the heath family Ericaceae, with a single species, Harrimanella hypnoides, also known as moss bell heather. It was originally named Cassiope hypnoides by Linnaeus (1737) in his Flora Lapponica, but Harrimanella hypnoides is now the accepted name at ITIS. The species name hypnoides means 'like Hypnum ', which is a genus mosses.

The flowers are conspicuous, white and bell shaped with five fused petals and five sepals. They are borne singly on short reddish pedicels. The fruit is an erect capsule.
