It is commonly known as '''crosswort''', '''smooth bedstraw''' or '''Luc na croise''' in Gaelic.<ref name=":0">{{Cite web|title=ITIS - Report: Cruciata laevipes|url=https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=Scientific_Name&search_kingdom=every&search_span=exactly_for&categories=All&source=html&search_credRating=All&search_value=Cruciata%20laevipes|access-date=2021-10-08|website=www.itis.gov}}</ref> The Latin epithet ''laevipes'' refers to the smooth stalk.

The common name crosswort is a 16th century translation of the botanists' Latin ''cruciata planta'', meaning "cross plant", i.e., with leaves in a cross-like arrangement.<ref>Grigson G. 1974. ''A Dictionary of English Plant Names''. Allen Lane. {{ISBN|0-71-390442-9}}</ref>
