"Tall Cool One" is a song by the English rock singer Robert Plant. It was written by Plant and keyboardist Phil Johnstone, who also co-produced Now and Zen. Former Led Zeppelin bandmate Jimmy Page plays guitar on the recording. It was the second single released from his fourth solo studio album Now and Zen (1988).
The song features guitar riff samples of Led Zeppelin songs, including "Black Dog", "Dazed and Confused", "Whole Lotta Love",
"The Ocean" and "Custard Pie", as well as lyrical references to "Black Dog" and "When the Levee Breaks".
Cashbox magazine called it a "smoking, balls-out rocker with a really unusual skew."
It reached No. 87 on the UK singles chart, No. 25 on the Billboard Hot 100 and No. 1 on the Billboard Mainstream Rock chart. It was Plant's fourth top of the chart rock single.
"Tall Cool One" was featured in a television advertisement for Coca-Cola.
