Who Was That Stranger is the twenty-first studio album by Loretta Lynn, released in 1988 on MCA Records. It was her final album for the label before a long recording hiatus that lasted until 1993.
The album included the single 'Who Was That Stranger', which peaked at number 57 on the Billboard Hot Country Songs chart. The record did not achieve major commercial impact but is remembered for its traditional country sound.
Recording sessions took place in Nashville, Tennessee, with production uncredited in available sources. After this album, Lynn took a break from recording until her return with 'Van Lear Rose' in 2004.
