First of the Big Bands is a studio album by Tony Ashton of Ashton, Gardner and Dyke and Jon Lord of Deep Purple, released in April 1974 by Purple Records in the UK and Europe and Warner Bros. Records in the US.

Stylistically, First of the Big Bands was the precursor to Paice Ashton Lord's Malice in Wonderland album from 1977.

Most of the album was recorded at Air and Apple Studios, London, with additional work being completed at De Lane Lea and Island.

In November 2010 a remastered edition of the album was released by Purple Records.

It contains two bonus tracks – the single B-side "Sloeback" and an alternative version of "Down Side Upside Down".
