Sunny Side Up is the second studio album by Scottish singer and songwriter Paolo Nutini, released on 29 May 2009 in Ireland and 1 June 2009 in the United Kingdom.

Nutini self-recorded the album with his band the Vipers, while Ethan Johns contributed to the mixing and production.

[8][9][10][11][12] On 19 February 2010, Colin Farrell presented Nutini with "Best International Album" for Sunny Side Up at the 2010 Meteor Awards.

[17] It is his second highest chart success and the biggest hit single from Sunny Side Up, spending 21 weeks inside the top 75.

AllMusic's Thom Jurek noted the move away from the sound of These Streets: "Nutini has taken huge chunks of America's (and Scotland's) pop and folk pasts and reshaped them in his own image," going on to describe it as "wise beyond this songwriter's years".

"[23] Neil McCormick of The Daily Telegraph was also positive, stating "his joyous second album organically blends soul, country, folk and the brash, horny energy of ragtime swing.

[22] Graeme Thomson of The Observer saw the album as an attempt by Nutini at "rebranding himself as a mongrel hybrid of John Martyn, Otis Redding and Bob Marley".
