Cephalanthera longifolia, common name the Sword-leaved Helleborine or Narrow-leaved Helleborine, is an herbaceous perennial plant with rhizome belonging to the family Orchidaceae.

The genus name Cephalanthera comes from the Greek cephalos (head) and antheros (anther), therefore means with round anthers. The Latin name longifolia means with long leaves .

Cephalanthera longifolia reaches on average 20–60 centimetres (7.9–24 in) of height in typical conditions. This orchid has erect and glabrous multiple stems. The leaves are dark green, long and narrow tapering (hence the common name of Sword-leaved Helleborine). The inflorescence consists of 8-20 bell-shaped flowers of about 1 cm in size. The flowers are white with a yellow-edged labellum and usually they are opened only during the warmest and brightest hours of the day. They can be found in bloom from April to June, depending on location and altitude. The flowers are pollinated by solitary bees and seeds are wind-dispersed.
