Solaranthus is an extinct genus of plants with contentious affinities which has been found fossilized in the Jiulongshan Formation of China. It dates to the middle Jurassic period.[1] It was first named by Shaolin Zheng and Xin Wang in 2010 and the type species is Solaranthus daohugouensis.[1]

Some authors interpret Solaranthus as an unusual angiosperm, while others consider it a cycadalean[2] or peltaspermalean pollen organ.[3]
