A Nice Pair is a compilation album by Pink Floyd, re-issuing their first two albums—The Piper at the Gates of Dawn and A Saucerful of Secrets—in a new gatefold sleeve. The album was released in December 1973 by Harvest and Capitol in the United States and the following month in the United Kingdom by Harvest and EMI. It reached number 36 in the US Billboard album charts, and was certified gold by the Recording Industry Association of America (RIAA) in March 1994.

There are a few differences between the US and UK issues on the first disc of this compilation. In the US Harvest Records and its distributor Capitol Records reconstructed their edition from tapes that had been previously altered for the debut 1967 US album Pink Floyd (the original U.S. title for Piper) and other recordings, which were cut from the UK version. As explained in a note on the back cover of the US edition of A Nice Pair, songs dropped from the US 1967 Pink Floyd album, "Flaming", "Astronomy Domine" and "Bike", are restored for this re-issue.

However, some of the restored songs appear in versions that are different from the UK Piper release: the eight-minute live Ummagumma recording of "Astronomy Domine" replaces the original four-minute studio recording; "Interstellar Overdrive" fades out slightly early (as it did on the US debut album) and adds a few seconds of silence before "The Gnome", rather than using a segue between these songs as found on the UK version; and "Flaming" is an alternate mix and edit which previously appeared on a US single, and the only track to appear on this album in mono. In later pressings, the correct stereo version of "Flaming" was restored, while the other songs continued to appear in the versions described here. The US version of this album was also released in Canada.
