The RGA420Z is an RGA series solid body electric guitar model introduced by Ibanez in 2010. It was made in Japan by FujiGen as part of the upscale Prestige line.

The RGA420Z features a flamed maple top with natural binding on a sculpted mahogany body bolted to a maple and walnut neck with a 24-fret rosewood fingerboard with dot position markers. Components include dual, covered Ibanez active humbucking pickups with an Active EQ control, an Edge Zero double locking tremolo bridge with a removable ZPS tuning stabilizer and Gotoh tuning machines.

The RGA420Z was among the first RGA models equipped with a tremolo, along with the seven string RGA427Z and the RGA220Z which is similar to the RGA420Z but lacks the flamed maple top.

The RGA420Z was discontinued after 2012.
