'''Scenedesmaceae''' is a family of green algae in the order Sphaeropleales. ''Scenedesmus'' algae are commonly found in freshwater plankton. The former family Coelastraceae is considered a synonym of Scenedesmaceae.<ref name="ITIS" >{{ITIS |id=6272 |taxon=Coelastraceae}}</ref>
The family has existed since at least the Cretaceous period, as evidenced by amber deposits from France containing the genus ''Enallax''.<ref>{{cite journal |last=Girard |first=Vincent |date=2009 |title=Evidence of Scenedesmaceae (Chlorophyta) from 100 million-year-old amber |journal=Geodiversitas |volume=31 |issue=1 |pages=145–151 |doi=10.5252/g2009n1a13 |s2cid=129466659 |url=https://sciencepress.mnhn.fr/en/periodiques/geodiversitas/31/1/presence-de-scenedesmaceae-chlorophytes-dans-un-ambre-vieux-de-100-millions-d-annees |access-date=27 November 2021 |archive-date=11 May 2021 |archive-url=https://web.archive.org/web/20210511231509/https://sciencepress.mnhn.fr/en/periodiques/geodiversitas/31/1/presence-de-scenedesmaceae-chlorophytes-dans-un-ambre-vieux-de-100-millions-d-annees |url-status=live |url-access=subscription }}</ref>
