<jats:p>Classification and relationships of the Ordovician encrinurines <jats:italic>Frencrinoides</jats:italic> Lespérance and Desbiens and <jats:italic>Walencrinoides</jats:italic> Lespérance and Desbiens are poorly understood, with little evidence for monophyly of either genus. We revise the type species of both genera, <jats:italic>F. capitonis</jats:italic> (Frederickson) and <jats:italic>W. rarus</jats:italic> (Walcott), using new and archival material. We explore their species composition and phylogenetic relationships with a parsimony analysis that includes 17 well-documented ingroup species that can be coded readily, and which is rooted with <jats:italic>Encrinuroides regularis</jats:italic> Parnaste, the oldest known encrinurine. The results support monophyly of <jats:italic>Frencrinuroides</jats:italic> and <jats:italic>Walencrinuroides</jats:italic>, albeit with more limited species membership than proposed by Lespérance and Desbiens. Previous suggestions that both <jats:italic>E. uncatus</jats:italic> Evitt and Tripp and <jats:italic>E. neuter</jats:italic> Evitt and Tripp should be assigned to <jats:italic>Erratencrinurus</jats:italic> Kruger are also supported by our analysis, as is monophyly of <jats:italic>Physemataspis</jats:italic> Evitt and Tripp. New species are <jats:italic>W. rolfi</jats:italic> and <jats:italic>W. tremblayi</jats:italic>.</jats:p>
