Bill Porter (born October 3, 1943) in Los Angeles is an American author who translates under the pen-name Red Pine (赤松, pinyin: Chì Sōng). He is a translator and interpreter of Chinese texts, primarily Taoist and Buddhist, including poetry and Sūtras.

He was raised in mountainous Idaho. After serving three years in the U.S. Army (refusing assignment in Vietnam and subsequently being reassigned as a clerk in Germany), he took a degree in anthropology from University of California, Santa Barbara and went on to graduate studies in language (Chinese) and anthropology at Columbia University, but dropped out in 1972 to go to the Fo Kwang Shan Buddhist monastery in Taiwan.

In the years following, he lived in Taiwan and Hong Kong. Since 1989 he has traveled extensively in China, both as a journalist and on his own. He adopted a Chinese pen-name (hào) "Red Pine" (赤松 "Chi Song"), after the legendary Taoist immortal. In 1993, after 22 years in East Asia, he returned to the US. In 1999 and 2000, he taught Buddhism and Taoism at the City of Ten Thousand Buddhas. He now lives in Port Townsend, Washington.

Pinus resinosa, commonly known as the red pine or Norway pine,[1] is pine native to North America. The Red Pine occurs from Newfoundland west to Manitoba, and south to Pennsylvania, with several smaller, disjunct populations occurring in the Appalachian Mountains in Virginia and West Virginia, as well as a few small pockets in extreme northern New Jersey and one in north central Illinois.

Red Pine is a coniferous evergreen tree characterized by tall, straight growth in a variety of habitats. It usually ranges from 20–35 m (65-115 ft) in height and 1 m (3 ft) in trunk diameter, exceptionally reaching 43 m (141 ft) tall[2]. The crown is conical, becoming a narrow rounded dome with age. The bark is thick and gray-brown at the base of the tree, but thin, flaky and bright orange-red in the upper crown; the tree's name derives from this distinctive character. Some red color may be seen in the fissures of the bark. Red Pine is self pruning; there tend not to be dead branches on the trees, and older trees may have very long lengths of branchless trunk below the canopy.
