Karl Hoschna (1876–1911) was a Tin Pan Alley-era composer most noted for his songs "Cuddle up a Little Closer, Lovey Mine", "Every Little Movement" and "Yama Yama Man", and for a string of successful Broadway musicals.
Hoschna was born on 16 August 1876 in Kuschwarda, Bohemia, and educated in Austria at the Vienna Conservatory of Music, specializing in the oboe. He graduated with honors and became an oboist in the Austrian army band. He emigrated to the United States in 1896 and joined the Victor Herbert orchestra as an oboe soloist.
Hoschna married Hettie Hug; they had three daughters.

With Otto Harbach, Harry B. Smith, Charles Noel Douglas, Mark Swan, Benjamin Hapgood Burt, William C. Duncan, and others, he collaborated on a series of Broadway musical comedies, which included:
