Prasiolaceae is a family of green algae in the order Prasiolales.See the NCBI [https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?mode=Info&id=135266 webpage on Prasiolaceae]. Data extracted from the {{cite web | url=http://ftp.ncbi.nih.gov/pub/taxonomy/ | title=NCBI taxonomy resources | publisher=National Center for Biotechnology Information | access-date=2007-03-19}} Members of this family are found in freshwater, terrestrial, and marine habitats.{{cite book|title= Taxonomy and biogeography of Macquarie Island seaweeds|last1= Ricker|first1=R.W.|date= 1987|pages= 1–344|publisher= British Museum (Natural History)|location=London|isbn= 0-565-00998-2}}

Algae in the family Prasiolaceae consist of thalli with blades a single cell thick (i.e. monostromatic). Vegetative cells are polygonal with two to four cells arranged within a parent cell wall. Each cell has a single, stellate chloroplast and a central pyrenoid.{{cite journal|title=Two new species of family Prasiolaceae (Prasiolales, Chlorophyta) from China Sea|last1= Luan|first1=R.|last2=Huang|first2=B.|last3=Ding|first3=L|last4=Luan|first4=S.|date=2009|journal= Acta Oceanologia Sinica|volume=28|issue=6|pages=118–122}}

Traditionally, it was the only family in the order Prasiolales. However, molecular phylogenetics have shown that additional algae with simple morphologies, such as Stichococcus, also belong to the same clade as this family.{{cite journal|doi=10.3390/plants13172405|doi-access=free |title=Prasiolopsis wulf-kochii (Prasiolales, Trebouxiophyceae), a New Species Occurring in Hairs of the Sloth Bradypus tridactylus |date=2024 |last1=Darienko |first1=Tatyana |last2=Pröschold |first2=Thomas |journal=Plants |volume=13 |issue=17 |page=2405 |pmid=39273889 |pmc=11397384 |bibcode=2024Plnts..13.2405D }}
