Michael John Gilmour Howlett (born 27 April 1950) is a bass guitar player, record producer and teacher based in the United Kingdom and Australia.

Howlett settled in London and in 1973 joined renowned British progressive rock group Gong, which had been founded by an Australian expatriate, Daevid Allen.

The band recorded several demos and played at a Paris Gong reunion concert in May 1977, but disbanded when Summers left to join Copeland and Sting's other project, the Police.

He produced many hit singles and albums for leading new wave music acts including A Flock of Seagulls, the Alarm, China Crisis, Martha and the Muffins, Orchestral Manoeuvres in the Dark, Stephen Duffy, Gang of Four and Comsat Angels.

In 1993, he launched a record label, Mauve, which released albums by singer-songwriters Rafa Russo, Debbie Cassell and Jay Fisher.
