The Bootleg Series Vol. 9: The Witmark Demos: 1962–1964 is a compilation album by American singer-songwriter Bob Dylan, containing demo recordings he made for his first two publishing companies, Leeds Music and M. Witmark & Sons, from 1962 to 1964. The seventh installment of the ongoing Bob Dylan Bootleg Series, it was released on October 19, 2010 on Legacy Records.

It features 47 tracks with Dylan accompanying himself on acoustic guitar, harmonica and occasionally piano. The recordings were only available on pirate recordings until 1991; three of these recordings appeared on the first volume of the series. A fourth demo of "Don't Think Twice, It's All Right" was included on The Bootleg Series Vol. 7: No Direction Home: The Soundtrack. While Dylan recorded subsequent versions of most of the songs, the album features 15 that were produced exclusively as demos and had never been heard before except as bootlegs.

The Witmark Demos was released in two formats: the standard two-disc set common to the rest of the series; and a four album set. Both releases featured a booklet with an account on the album's significance by historian Colin Escott, along with photos of Dylan from the period when the demos were recorded. The album peaked at number 12 on the Billboard 200 albums chart in its first week, becoming Dylan's 20th album to debut in the top 20.
