Thomas Linley (17 January 1733 – 19 November 1795) was an English bass and musician active in Bath, Somerset. Born in Badminton, Gloucestershire, Linley began his musical career after he moved to Bath at age 11 and became apprentice to the organist Thomas Chilcot. After his marriage to Mary Johnson in 1752, Linley at first supported his wife and growing family predominantly as a music teacher. As his children grew and he developed their musical talent, he drew an increasing amount of income from their concerts while also managing the assembly rooms in Bath. When the new Bath Assembly Rooms opened in 1771, Linley became musical director and continued to promote his children's careers. He was eventually able to move to London with the thousands of pounds which he had amassed from their concerts.
Among Linley's students were his eight children (Elizabeth Ann, Thomas, Mary, Samuel, Maria, Ozias, William, and Jane), as well as tenor Charles Dignum, singer and actress Anna Maria Crouch, and novelist Frances Sheridan. Linley collaborated with his son Thomas in penning the comic opera The Duenna, with libretto by his son-in-law Richard Brinsley Sheridan.
