::summary Species of plant ::

Athyrium niponicum, the Japanese painted fern, is a species of fern native to eastern Asia.

This species was redefined as a member of genus Anisocampium in 2011 based on phylogenetic analyses, but the genus has since been sunk into Athyrium.

This deciduous fern has a creeping rhizome and a tuft-shape array of fronds. The fronds are variable in length, generally 30 to 75 centimeters long but occasionally over a meter in length. They have alternately arranged, subdivided pinnae. The spore-bearing sori on the undersides of the fertile pinnae are variable in shape, being "oblong, hooked, J-shaped, or horseshoe-shaped".

The Latin specific epithet niponicum means "relating to Japan (Nippon)".

This is a commonly cultivated fern, especially A. niponicum var. pictum. It thrives in many kinds of shady garden conditions and produces thick colonies of gray-green fronds with reddish midribs. 'Pictum' is also considered to be a cultivar; varieties and cultivars are bred to achieve midribs in many shades of red.

A. niponicum var. pictum has gained the Royal Horticultural Society's Award of Garden Merit.{{cite web | url= https://www.rhs.org.uk/Plants/92151/i-Athyrium-niponicum-i-var-i-pictum-i/Details |title = RHS Plantfinder - Athyrium niponicum var. pictum | publisher = Royal Horticultural Society | accessdate=12 January 2018}} as has the cultivar 'Silver Falls'.{{cite web | url= https://www.rhs.org.uk/Plants/168821/i-Athyrium-niponicum-i-var-i-pictum-i-Silver-Falls/Details | title = RHS Plantfinder - Athyrium niponicum var. pictum 'Silver Falls' | publisher = Royal Horticultural Society | accessdate = 19 January 2018}}
