Perfect Grade (PG) (パーフェクトグレード Pāfekuto Gurēdo) a line of 1/60 scale Gunpla kits of the Mobile Suits in the Gundam meta series. The PG line originated with the release of the Perfect Grade Evangelion EVA-01 in 1997. The line was then exclusive to the Gundam franchise from 1998 to 2017, until Bandai announced the Perfect Grade 1/72 scale Millennium Falcon for the Star Wars franchise. The PG line has significant external and internal details plus light up gimmicks with LEDs. The PGs are some of the most expensive Gunpla produced and have often been used to develop Master Grade and Real Grade technology.

In 2020, Bandai introduced a new sub-line Perfect Grade Unleashed to commemorate the 40th anniversary of Gunpla, featuring kits with increased complexity and diecast metal parts.
