Long pepper (Piper longum), sometimes called Javanese Long Pepper, Indian Long Pepper or Indonesian Long Pepper, is a flowering vine in the family Piperaceae, cultivated for its fruit, which is usually dried and used as a spice and seasoning.

Long pepper is a close relative of the black pepper plant, and has a similar, though generally hotter, taste. The word pepper itself is derived from the Sanskrit word for long pepper, pippali. The fruit of the pepper consists of many minuscule fruits — each about the size of a poppy seed — embedded in the surface of a flower spike; it closely resembles a hazel tree catkin. Another species of long pepper, Piper retrofractum, is native to Java, Indonesia.
