"No Doubt About It" is a May 1980 single by the British pop group Hot Chocolate.

It became their highest-charting hit of the 1980s, peaking at number 2 on the UK Singles Chart, a position "You Sexy Thing" had also reached five years before.

The two songs are, however, outdone by their 1977 chart-topper, "So You Win Again", which was Hot Chocolate's only Number 1 single in the UK.

[2] The tune was written by Mike Burns, Steve Glen and David Most (the brother of the band's manager, Mickie Most).

[3] The song was remixed by Frank Mono and released as a single for a second time in 1988.
