Alistair Jardine "Ali" McMordie (born 31 March 1959 in Belfast, Northern Ireland) is a bass guitarist, best known as a founding member of Stiff Little Fingers, playing with the band from 1977 until they broke up in 1983,[1] and joined them on the first few years of reunion tours five years later.

After Stiff Little Fingers disbanded in 1983, McMordie joined a group of Reading musicians in the newly formed dance-punk band, Friction Groove.

They secured a deal with Warner label, Atlantic, and went on to record an album - The Black Box - in Berlin and Brussels, from which the first single ("Time Bomb") charted very briefly.

Around 1986 he provided, along with other Friction Groove members, the core band behind Sinéad O'Connor, who had just arrived in London from Dublin.

Since 1994 he has been the tour manager for American artist Richard Hall AKA Moby (with whose band he has sometimes played bass).
