Ina Souez (June 3, 1903 – December 7, 1992) was an American soprano and jazz singer who made her career in the United Kingdom.
She studied under Florence Hinman in Denver, and in 1931 traveled to Europe, taking further lessons with Sofia del Campo in Milan.
Her performance was sensationally received, and the Royal Opera House quickly engaged her for the upcoming season; this created a problem for Glyndebourne, as they had taken it for granted that she would return and so had not bothered signing her up for the following festival year.
She also sang Donna Anna for Glyndebourne, in 1936, and appeared in Stockholm and The Hague as well before returning to the United States on the outbreak of World War II.
Of the experience, she said that Jones "was offering me some real money"; she remained with him for more than ten years before retiring to teach voice in San Francisco and Los Angeles.
