Peter Bernhard Kyne (October 12, 1880 – November 25, 1957) was an American novelist who published between 1904 and 1940. He was born and died in San Francisco, California. Many of his works were adapted into screenplays starting during the silent film era, particularly his first novel, The Three Godfathers, which was published in 1913 and proved to be a huge success. More than 100 films were adapted from his works between 1914 and 1952, many of the earliest without consent or compensation. Kyne also created the character of Cappy Ricks in a series of novels.
The son of cattle rancher John Kyne and Mary Cresham, young Kyne worked on his father's ranch then attended a business college where he decided to become a writer.
When still younger than 18 years old, he lied about his age and enlisted with Company L, 14th U.S. Infantry nicknamed "the Golden Dragons", which served in the Philippines from 1898 to 1899. The Spanish–American War and the following insurrection of General Emilio Aguinaldo provided background for many of Kyne's later stories. During World War I, he served as a captain of Battery A of the California National Guard 144th Field Artillery Regiment, known as the "California Grizzlies".

- A wooden sign in Sequoia Park in Eureka, California, bears a quote from Kyne's The Valley of the Giants: "I'm not going to cut the timber in this valley. I haven't the heart to destroy God's most wonderful handiwork. 'Twas in her mind to give her Valley of the Giants to Sequoia (Eureka) for a city park." In Kyne's Humboldt-inspired book The Valley of the Giants, a timber baron's wife's wish of saving a favorite stand of redwoods and creating a park in the middle of a city is made possible by her husband after her death.
