James Whitcomb Riley (October 7, 1849 – July 22, 1916) was an American writer, poet, and best-selling author. During his lifetime he was known as the "Hoosier Poet" and "Childrens' Poet" for his dialect works and his poetry for children. His poems tend to be humorous or sentimental. Of the approximately 1,000 poems Riley wrote, the majority are in dialect. His famous works include "Little Orphant Annie" and "The Raggedy Man".

Riley began his career writing verses as a sign maker and submitting poetry to newspapers. Thanks in part to poet Henry Wadsworth Longfellow's endorsement, he eventually earned successive jobs at Indiana newspaper publishers during the late 1870s. He gradually rose to prominence during the 1880s through his poetry reading tours. He traveled a touring circuit first in the Midwest, and then nationally, appearing either alone or with other famous talents. During this period Riley's long-term addiction to alcohol began to affect his performing abilities, and he suffered financially as a result. However, once he extricated himself from a series of poorly negotiated contracts that sought to limit his earnings, he began to accumulate wealth and eventually became a financial success.

By the 1890s, Riley had become known as a bestselling author. His children's poems were compiled into a book illustrated by Howard Chandler Christy. Titled Rhymes of Childhood, it was his most popular and sold millions of copies. As a poet, Riley achieved an uncommon level of fame during his lifetime. He was honored with annual Riley Day celebrations around the United States and was regularly called on to perform readings at national civic events. He continued to write and hold occasional poetry readings until a stroke paralyzed his right arm in 1910.

Riley's chief legacy was his influence in fostering the creation of a Midwestern cultural identity and his contributions to the Golden Age of Indiana Literature. With other writers of his era, he helped create a caricature of Midwesterners and formed a literary community that produced works rivaling the established eastern literati. There are many memorials dedicated to Riley, including the James Whitcomb Riley Hospital for Children.

James Whitcomb Riley was born on October 7, 1849, in the town of Greenfield, Indiana, the third of the six children of Reuben Andrew and Elizabeth Marine Riley. Riley's grandparents came from Ireland to Pennsylvania before moving to the Midwest Riley's father was an attorney, and in the year before his birth, he was elected a member of the Indiana House of Representatives as a Democrat. He developed a friendship with James Whitcomb, the governor of Indiana, after whom he named his son. Martin Riley, Riley's uncle, was an amateur poet who occasionally wrote verses for local newspapers. Riley was fond of his uncle who influenced his interest in poetry.

Shortly after his birth, the family moved into a larger house in town. Riley was "a quiet boy, not talkative, who would often go about with one eye shut as he observed and speculated". His mother taught him to read and write at home before sending him to the local community school in 1852. He found school difficult and was frequently in trouble. Often punished, he had nothing kind to say of his teachers in his writings. His poem "The Educator" tells of an intelligent but sinister teacher and may have been based on one of his instructors. Riley was most fond of his last teacher, Lee O. Harris. Harris noticed Riley's interest in poetry and reading and encouraged him to pursue it further.

Riley's school attendance was sporadic, and he graduated from grade eight at age 20 in 1869. In an 1892 newspaper article, Riley confessed he knew little of mathematics, geography, or science, and his understanding of proper grammar was poor. Later critics, like Henry Beers, pointed to his poor education as the reason for his success in writing; his prose was written in the language of common people which spurred his popularity.

Riley lived in his parents' home until he was 21 years old. At age five, he began spending time at the Brandywine Creek near Greenfield. His poems "A Barefoot Boy" and "The Old Swimmin' Hole" refer to his time there. As a child he was introduced to many people who later influenced his poetry. His father regularly brought home clients and disadvantaged people to help them. Riley's poem "The Raggedy Man" is based on a German tramp his father hired to work at the family home. Riley picked up the cadence and character of the dialect of central Indiana from travelers along the old National Road. Their speech greatly influenced the hundreds of poems he wrote in 19th century Hoosier dialect.
