Xingxueanthus is an extinct genus of plants of dubious affinity which existed in China during the middle Jurassic period.[1] It was first named by Xin Wang and Shijun Wang in 2010 and the type species is Xingxueanthus sinensis.[1]

Xingxueanthus is known only from a single specimen of carbonized inflorescence. There is debate as to the taxonomic position of Xingxueanthus, being either an early Angiosperm, a new class of Gymnosperm, or a poorly preserved conipherophyte cone.[2]
