Thymophylla tenuiloba, also known as the bristleleaf pricklyleaf, Dahlberg daisy, small bristleleaf pricklyleaf, golden fleece, or shooting star, is a bushy, multi-branched flowering annual from the family Asteraceae. Native to south central Texas and northern Mexico, it produces a large number of small, yellow flowers and demonstrates a trailing habit. It is tolerant of heat and dry conditions and is sometimes sold as a summertime annual plant in areas beyond its native range.

The plant was once known as Hymenatherum tenuilobum in the De Candolle system.

The species is naturalized in Queensland in Australia.
