The Land of Smiles is a 1929 operetta by Franz Lehár and is set in China. The heroine Lisa is a European girl who marries a Chinese visitor and returns with him to his homeland despite the warnings of her friends and family, but eventually finds she is unable to come to terms with his native culture.

This was one of Lehár's later works, and has a bittersweet ending which the Viennese loved. Prince Sou-Chong is left alone, while his beloved Lisa returns to her homeland. His sister, Princess Mi had also become attached to the Viennese official, Gustl and so the ending is doubly sad.
