Sinclair Beiles (b. Kampala, Uganda, 1930–2000, Johannesburg) was a South African beat poet and editor for Maurice Girodias at the Olympia Press in Paris.

Beiles attributed his subsequent mental instability to this experience even though he insisted that Takis provide him with a helmet to protect his head from the magnetic field.

In later life he returned to South Africa and was associated with the Johannesburg-based Gallery III [1] group of poets, writers, composers and performance artists.

The poet had a burst of writing activity from 1991 to 2000, publishing a large number of poetry collections, including A South African Abroad (Lapis Press, 1991).

The independent filmmaker Anton Kotze made a short film called "Sacred Fix" (26 minutes, South Africa, 1997), which is a documentary portrait of Sinclair Beiles.
