Sina (sometimes known as "Sina Evil" or "Sina Sparrow") is an artist, cartoonist and zinester from the UK.
In 1993 Sina created and self-published the zine Concerned Müthers, aimed at "queer teens and their strait mates". Seven issues of the zine were released, until Sina ceased publication in 1995. This was quickly followed by the highly-acclaimed, primarily autobiographical BoyCrazyBoy.
Sina has also contributed to a number of zines, including Boy Trouble. His work can regularly be seen in the anthology The Book of Boy Trouble Volumes 1 and 2.
