Hot Line (subtitled The Tenor of Bill Barron) is an album by saxophonist Bill Barron which was recorded in 1962 and first released on the Savoy label. The album was also rereleased as The Hot Line under Booker Ervin's co-leadership.

In his review on Allmusic, Scott Yanow called it a "fine release" stating "Barron's five advanced originals alternate with three standards that give the two tenors an opportunity to display their contrasting but complementary inside/outside styles"

All compositions by Bill Barron except where noted.
