Air Cuan Dubh Drilseach is a science fiction novel written in Scottish Gaelic by Tim Armstrong and published by CLÀR in 2013.

The central conceit of the novel is that in space, everyone speaks Gaelic, allowing the author to create an entirely Gaelic-speaking world for the characters.

[3][4] Air Cuan Dubh Drilseach was launched at a series of events in three separate locations: at the Aye Write book festival in Glasgow with Aonghas 'Dubh' MacNeacail presiding; at two punk rock gigs on the same day in Edinburgh; and at Sabhal Mòr Ostaig on the Isle of Skye at an event also marking the launch of Meg Bateman's new book of poetry, Transparencies.

played out a 3–3 draw against St. Mirren F.C., inadvertently diverting police resources at a crucial time and allowing the anarcho-punk, Oi!, punk rock, street celebration to continue uninhibited, proving a significant landmark in Gaelic culture.

"[9] In 2016, Air Cuan Dubh Drilseach was selected by Scot Lit Fest as one of the five most important Gaelic novels of all time.
