Halcyon (Best of) is a compilation album by the British electronica duo Orbital featuring a selection of singles from their career together, it was released in 2005.

Though the group's "official" greatest hits album Work 1989-2002 had been released three years earlier, in 2005 the band's parent label Warner decided to release a Platinum series of "Best of" albums.

The album was specifically created for and released in the North American market; Orbital's official website Loopz even goes so far as to dub the album "USA Best of".

Some retailers also list the album as Halcyon: The Platinum Collection.
