A Lullaby to the Sorrowful Mystery () is a 2016 historical fantasy drama film directed by Lav Diaz. A co-production between the Philippines and Singapore, the film competed for the Golden Bear at the 66th Berlin International Film Festival, eventually winning the Alfred Bauer Prize. It was theatrically released in the Philippines by Star Cinema.
The film received mixed reviews from critics, with criticism mostly directed towards its pacing and confusing narrative. Guy Lodge of Variety states in his review that "A major disappointment from a major filmmaker, Diaz's latest super-sized tapestry of historical fact, folklore and cine-poetry is typically ambitious in its expressionismâÂÂbut sees the helmer venturing into the kind of declamatory, didactic rhetoric that his recent stunners Norte, the End of History and From What Is Before so elegantly avoided."
