Primuloideae is a subfamily of the family Primulaceae in the order Ericales.{{Cite journal |last1=de Luna |first1=Bruna Nunes |last2=Freitas |first2=Maria de Fátima |last3=Barros |first3=Claudia Franca |date=26 October 2018 |title=Diversity of leaf secretory structures in five Neotropical genera of Primulaceae: ecological aspects and evolutionary significance |url=http://www.nrcresearchpress.com/doi/10.1139/cjb-2018-0114 |journal=Botany |language=en |volume=97 |issue=1 |pages=35–51 |doi=10.1139/cjb-2018-0114 |s2cid=92217578 |issn=1916-2790|url-access=subscription }} Formerly it represented the Primulaceae family (Primulaceae s.s.), before the latter was enlarged (Primulaceae s.l.) by addition of three other closely related families that formerly represented the order Primulales.

Subfamily is characterised by scapose inflorescences, distinctly tubular flowers having campanulate or hypocrateriform corolla, imbricate corolla aestivation, isodiametric corolla epidermal cells, leaves almost always forming a basal rosette and ovules rarely immersed in the placenta. In addition they often have syncolpate or sometimes polycolpate pollen, without margo.{{Cite journal |last=Källersjö |first=Mari |last2=Bergqvist |first2=Gullevi |last3=Anderberg |first3=Arne A. |date=2000 |title=Generic realignment in primuloid families of the Ericales s.l.: a phylogenetic analysis based on DNA sequences from three chloroplast genes and morphology |url=https://bsapubs.onlinelibrary.wiley.com/doi/10.2307/2656725 |journal=American Journal of Botany |language=en |volume=87 |issue=9 |pages=1325–1341 |doi=10.2307/2656725 |issn=1537-2197|url-access=subscription }}
