Meilifeilong () is an extinct genus of chaoyangopterid pterosaurs from the Early Cretaceous Jiufotang Formation of China. The genus contains two species. The type species, M. youhao, was described in 2023 based on an almost complete skeleton and a partial isolated skull. The second species, M. sanyainus, was described earlier in 2023 as a species of Shenzhoupterus, based on a complete skull and skeleton. Meilifeilong is the best-preserved and most complete chaoyangopterid currently known.
