Nadine Muriel, Countess of Shrewsbury (neé Crofton 24 January 1913 – 2003), known professionally as Nadine Talbot and later as Nadine Credi, was an English opera soprano and the first wife of John Chetwynd-Talbot, 21st Earl of Shrewsbury (1914–1980). They married in 1936.
Her father was Brigadier-General Cyril Randell Crofton, of Trobridge, Crediton.
She promoted two seasons of Opera at Ingestre in 1957 and 1958, an opera festival at Ingestre Hall, the couple's home.
Lord Shrewsbury sued for divorce in 1958, claiming that Nadine had been sexually involved with their daughters' tutor Anthony Lowther, but in 1959 judge Charles A. Collingwood rejected the divorce suit, finding that Lord Shrewsbury had committed adultery with Nina Mortlock. In a subsequent proceeding, a divorce was granted.
Lord Shrewsbury's second wife was Nina Mortlock.
Nadine and Lord Shrewsbury had six children. They had four daughters before the birth of an heir, Charles. He succeeded to the earldoms in 1980.
