"Be My Number Two" is a song by British singer-songwriter and musician Joe Jackson, released in 1984 as the third and final single from his sixth studio album Body and Soul.

"[6] On its release as a single, Jerry Smith of Music Week wrote, "A slow ballad sung with feeling, mainly accompanied by piano until the band come in at the end with a warm fluid sax picking out the melody.

[8] Frank Edmonds of the Bury Free Press gave the song an 8 out of 10 rating and described it as a "quiet, plaintive, thoughtful and extremely attractive love ballad".

[9] Sunie of Number One commented, "This is a pretty enough song, all tinkling piano and sad, cynical words.

"[10] Billboard noted, "A quiet tune, except for the rousing finish; just Jackson, piano, and a tone of bewildered pathos.
