Word of Mouth is the twenty-first studio album by the English rock group the Kinks.

The track "Living on a Thin Line" by Dave Davies was played three times in the 2001 episode "University" of the American TV show The Sopranos.

According to producer Terence Winter on the DVD extras, it is the series' most asked-about song.

The song "Good Day" includes an allusion to the death of actress Diana Dors.

Three tracks ("Going Solo", "Missing Persons", and "Sold Me Out") were repurposed for Kinks leader Ray Davies' solo debut album, the soundtrack to his concurrently produced, self-directed film, Return to Waterloo.
