3-Fluoro-alpha-PHP (3F-PHP) is a substituted cathinone derivative with stimulant effects which has been sold as a designer drug. It was first identified in Sweden in 2020 and continues to be detected in seized drug samples, though it appears to have been less widely used than related compounds such as 3F-PVP and 3F-PiHP.{{cite book | url = https://www.emcdda.europa.eu/system/files/publications/13464/20205648_TD0320796ENN_PDF_rev.pdf | title = New psychoactive substances: global markets, glocal threats and the COVID-19 pandemic.
