The Tree of Seasons is a children's book written by Stephen Gately and published posthumously by Hodder & Stoughton in 2010.

It follows the adventures of three siblings - Josh, Michael and Beth Lotts - who are on their summer holidays, and is said to be similar in style to the works of Enid Blyton, C. S. Lewis and Walt Disney.

[2] Following Gately's death in Spain in October 2009, the final drafts of The Tree of Seasons were completed in collaboration with June Considine and Jules Williams, with Andrew Cowles writing the acknowledgements.

[8] Irish Independent reviewer Sarah Webb remarked: "For a young man with no previous writing experience, the Tree of Seasons is quite an achievement" and "would make, with the addition of some powerful songs, an excellent musical".

[2] Sunday Tribune reviewer Pat Nugent compared it to Enid Blyton's The Faraway Tree series, remarked on "a host of kinks and clumsy moments that could have been fixed with relative ease", but said there was "a distinct possibility [Gately's] career as a children's author would have outpaced his status as a popstar".
