Plamo-Kyoshiro (プラモ狂四郎, Puramo Kyōshirō) is a manga series created and written by Hisashi Yasui and illustrated by Koichi Yamato.

Part of Sunrise's Gundam Franchise, it was first serialized in Kodansha's Shōnen magazine Comic BomBom from August 20, 1982 until December 17, 1986, compiling up to 15 tankobon volumes.

In addition to that, the manga contained original designs that would later inspire the Mobile Suit Variations and BB Senshi series.

Plastic models from other popular franchises also make appearances in Plamo-Kyoshiro, including those from Votoms, Dunbine, Dougram, Vifam, L-Gaim, Xabungle, Baldios, Star Wars, The Exorcist, Thunderbirds and Blue Thunder.

The success of Plamo Kyoshiro marked a trend at the time of its publication and several publishers wanted to have a manga based on battles of plastic models.
