Inez Hogan was an American writer and illustrator of children's books, particularly animal stories. She was born in Washington, D.C., and attended the Cape Cod School of Art. She lived in Provincetown, Massachusetts, and New York City.

Born in Washington, D.C., Hogan spent her early years in the city. After the end of World War I, Hogan became an acquaintance of aspiring scenic designer Cleon Throckmorton and other Southern artists later associated with George Cram "Jig" Cook's and Susan Glaspell's Provincetown Players. During this period, Hogan became a habitué of The Krazy Kat, an art colony, coffeehouse, and speakeasy located in the back alleys of the nation's Capitol. She later permanently relocated to Provincetown, Massachusetts.

During Prohibition in the United States, Hogan operated the only casino-nightclub and speakeasy available in Provincetown. Located on the town's wharf and accordingly titled "The Ship," the nightclub became a gathering place for artists, thespians, and other persons affiliated with the Provincetown Players' Wharf Theatre. Following the end of Prohibition in December 1933, Hogan continued to operate the casino-nightclub, offering drinking and gambling to boisterous crowds on the waterfront.

From the late 1930s until her death, children's books were purportedly her sole means of support. Of this she said "I can think of no happier way to make a living."

Hogan wrote 63 books, including many about her character Nicodemus. She illustrated another 19 books, including the first edition of Epaminondas and His Auntie by Sara Cone Bryant. The black characters in Hogan's books were often portrayed with African American stereotypes.

Inez Hogan died in February 1973 in Orleans, Massachusetts.
