Ram Nath Kak (1917–1993) (Kashmiri: राम नाथ काक (Devanagari)) (born in Srinagar and died in Honolulu) was a Kashmiri veterinarian whose autobiography Autumn Leaves is one of the most vivid portraits of life in 20th century Kashmir and has become a sort of a classic. The book was termed enthralling reading by the English writer Taya Zinkin.
The historian Ravinder Kumar said of the book: "The spirit of the Kashmiri people and their extraordinary ability to refashion lives of dignity and creativity for themselves comes across even more powerfully than the tragedy which has overtaken this beautiful valley in Shri Kak's account of his life and times."
