"All That I Need" is the third single from Irish boy band Boyzone's third studio album, Where We Belong (1998).

It was written and produced by Carl Sturken and Evan Rogers with remix and additional production by Rude Boy, Andy Bradfield, Trevor Steel, and John Holliday.

This made it their first original single release not to be co-written by any members of the group.

A reviewer from Music Week noted that the band "move ever further from Osmonds covers territory to adult respectability.

"All That I Need", containing a notably sensitive vocal from Ronan Keating, is the first evidence of a more mature sound for their forthcoming album Where We Belong, due out at the end of this month.
