Porter Steele (December 12, 1880 – December 20, 1966) was an American lawyer and composer, renowned for his composition of the march and later jazz standard "High Society." Born in Natchez, Mississippi, Steele was the eldest of five children to Hiram Roswell Steele, who served as Attorney General of Louisiana before relocating to Natchez and later Brooklyn to continue his legal practice.

Steele pursued his education at Yale University, graduating in 1902, where he composed "High Society" in 1901. This piece became a significant standard, recorded by various military and jazz bands, including those led by Alphonse Picou, Charles A. Prince, and King Oliver. His other notable composition includes "The Lobster's Promenade."

After graduating from Columbia Law School, Steele practiced law in New York City until his retirement in the 1930s. Following his retirement, he dedicated his time to music, farming, and other interests. Steele passed away in South Plainfield, New Jersey, in 1966 at the age of 86. His contributions to music, particularly through "High Society," have left a lasting impact on both military and jazz music genres.
