Katakuri (Erythronium japonicum; Japanese: 片栗) is a pink-flowered species trout lily, belonging to the Lily family and native to Japan, Korea and northeastern China. It is a spring ephemeral, blooming April–June in woodlands.

Applying the name trout lily may be somewhat of a misnomer, because in the Japanese species, the individual plant may or may not exhibit the flecked dark markings on the leaves, which is emblematic of that common name (see gallery below).
