Blepharismidae is a family of unicellular ciliate protists found in fresh and salt water. Two genera are recognized: Blepharisma , which contains some model organisms, and Pseudoblepharisma (monotypic in most sources) ^{[1] [2]}

Parablepharisma was part of the family, but more careful inspection (morphological and molecular) has placed it in a separate class distinct from the heterotrichs. ^[3] Acquisition of ribosomal sequences from Pseudoblepharisma in 2021 and 2022 also produces phylogenetic results incongruent with current taxonomy, instead placing the genus sister to Spirostomum . ^[4]
