The splendid fairywren (Malurus splendens) is a passerine bird in the Australasian wren family, Maluridae.

The habitat of the splendid fairywren ranges from forest to dry scrub, generally with ample vegetation for shelter. Unlike the eastern superb fairywren, it has not adapted well to human occupation of the landscape and has disappeared from some urbanised areas. The splendid fairywren mainly eats insects and supplements its diet with seeds.
