Across the Black Waters is an English novel by the Indian writer Mulk Raj Anand first published in 1939. It describes the experience of Lalu, a sepoy in the Indian Army fighting on behalf of Britain against the Germans in France during World War I. He is portrayed by the author as an innocent peasant whose poor family was evicted from their land and who only vaguely understands what the war is about. The book has been described as Anand's best work since the Untouchable.
