"Wonderboy" (sometimes spelled "Wonder Boy")[1] is a song by the English rock band the Kinks, written by Ray Davies.

Ray Davies composed "Wonderboy" over a single night in March 1968, during which he later recalled drinking an entire bottle of vodka.

[5][a] He commented, "I was expecting my second daughter, Victoria, and in that song is all the layers, the cathartic feelings, the problems, the images, my thoughts on my position in the world, why I should be a parent...

[9] Ray produced the song, while one of Pye's in-house engineer operated the four-track mixing console, likely Brian Humphires.

[11] Derek Johnson of New Musical Express called it a "charming philosophic song", displaying Ray's "incredible flair for writing lyrics of a beautifully descriptive nature".

[11] Johnson concluded that the song was more commercial than either "Waterloo Sunset" or "Autumn Almanac" and predicted it would be a big hit, as did Melody Maker's reviewer.

Billboard's critic characterised the song as an "infectious rocker loaded with teen appeal", leading Doug Hinman, a Kinks researcher, to suspect that the reviewer had not actually listened to the record.

[19] By the time "Autumn Almanac" was released in late 1967, American record stores had generally stopped stocking the band's singles.
