A wooden fish (Chinese: 木魚, pinyin: mùyú), (Vietnamese: mộc ngư), (Japanese: mokugyo (木魚^?)), (Korean: moktak 목탁), (Tibetan: ཤིང་ཉ།, Wylie: shingnya) sometimes known as a Chinese block, is a wooden percussion instrument similar to the Western wood block^{[citation needed]}. The wooden fish is used by monks and laity in the Mahayana Buddhist tradition. It is often used during rituals usually involving the recitation of sutras, mantras, or other Buddhist texts. The wooden fish is mainly used by Buddhist disciples in China, Japan, Korea, and other East Asian countries where the practice of Mahayana, such as the ceremonious reciting of sutras, is prevalent. In most Zen/Ch'an Buddhist traditions, the wooden fish serves to keep the rhythm during sutra chanting. In Pure Land Buddhism, it is used when chanting the name of Amitabha.

The Taoist clergy has also adapted the wooden fish into their rituals.

There are two kinds of wooden fish.

Most commonly today, it is the traditional instrument that is round in shape and often made out of wood (often made out of lumber); this form is actually a later development from the original. The fish is hollow with a ridge outside of the wooden fish to help provide the genuine hollow sound when striking the fish (the instrument is similarly shaped like a jingle bell). The sound can differ amongst wooden fish depending on the size, type of wood used, and how hollow the wooden fish is. The instrument is carved with fish scales on its top, and a carving of two fish heads embracing a pearl on the handle (to symbolize unity), hence the instrument is called a wooden fish for that reason. In Buddhism the fish, which never sleeps, symbolizes wakefulness. Therefore, it is to remind the chanting monks to concentrate on their sutra. Often the mallet used to strike the fish has a rubber coated tip to provide a muffled, but clear sound when struck. A simplified form is given in the temple block.

Sheng Yen (聖嚴; Pinyin: Shèngyán, birth name Zhang Baokang, 張保康) (December 4, 1930 – February 3, 2009) was a Buddhist monk, a religious scholar, and one of the mainstream teachers of Chinese Chan Buddhism. He was the 57th generational descendant of Linji in the Linji (Japanese: Rinzai) School and a 3rd generational descendant of Master Hsu Yun. In the Caodong (Japanese: Sōtō) lineage, Sheng Yen was the 52nd generational descendant of Master Dongshan (807-869), and the direct descendant of Master Dongchu (1908–1977).

Sheng Yen was the founder of the Dharma Drum Mountain, a Buddhist organization based in Taiwan. During his time in Taiwan, Sheng Yen was well known as one of the progressive Buddhist teachers who sought to teach Buddhism in a modern and Western-influenced world. In Taiwan, he was one of four prominent modern Buddhist masters, along with Masters Hsing Yun, Cheng Yen and Wei Chueh. In 2000 he was one of the keynote speakers in the Millennium World Peace Summit of Religious and Spiritual Leaders held in the United Nations.
