Euphrasia ruptura (former synonym: "Euphrasia sp. Tamworth") is a presumed extinct plant from the genus Euphrasia (eyebrights) within the family Orobanchaceae (formerly Scrophulariaceae) . It was first descriped in 1997 by William R. Barker from a single collection made in the Tamworth Area, Northern Tablelands, New South Wales in 1904. It is named after the Australian botanist Herman Montague Rucker Rupp who discovered this species.
