Eric Wrixon (29 June 1947 – 13 July 2015) was a musician from Belfast, Northern Ireland, and a founding member of Them and Thin Lizzy. He came up with the band name "Them" (from the 1954 sci-fi film Them!), but as he was a minor his parents declined to sign a recording contract on his behalf and he was replaced in July 1964 prior to recording with the band. By August 1965, he had completed his studies and very briefly returned to Them. Wrixon died on 13 July 2015 in Italy at the age of 68.
