Nepenthes andamana is a tropical pitcher plant endemic to Phang Nga Province, Thailand, where it grows near sea level in coastal savannah and grassland. It is thought to be most closely related to N. suratensis.

The specific epithet andamana refers to the Andaman Sea coast of Thailand.

Nepenthes andamana was formally described by Marcello Catalano in his 2010 book, Nepenthes della Thailandia: Diario di viaggio. The description was reviewed by Alastair Robinson, while Andreas Fleischmann provided the Latin translation.Catalano 013395 was designated as the holotype. This specimen was collected by Catalano in 2009 at sea level from Takua Pa, Phang Nga Province, Thailand. It is deposited at the Chulalongkorn University Herbarium (BCU).

Nepenthes andamana is a climbing plant growing to a height of approximately 3 m. The stem is and around 5 mm in diameter. Internodes are up to 3.5 cm long. The stem ranges in colour from green to red.

Leaves are and in texture. The lamina (leaf blade) is linear to , measures up to 30 cm in length by 3.5 cm in width, and is around 0.5 mm thick. Its apex is acute to narrowly and it is at the base, clasping the stem for around three-quarters of its circumference. Three longitudinal veins are present on either side of the midrib, restricted to the distal quarter of the lamina. veins are also visible, and arise obliquely from the midrib. Tendrils are up to 18 cm long and 2.5 mm in diameter. They are coiled in upper pitchers. The laminae are light green and commonly have a reddish hue, whereas the midrib and tendrils vary from green to red.
