Langgai Tinggang (other names also include Langgai Tinggan, Langgi Tinggang, Mandau Langgi Tinggan) is a traditional sword of the Sea Dayak people, originating from Borneo.

The name Langgai Tinggang means "the longest tail-feather of a hornbill".

[1][2] This sword is almost identical to Niabor, but with a hilt resembling that of Mandau.

On both sides a broad rib runs from the finger guard to the tip.

The finger guard is smaller than of the Niabor and is further removed from the hilt.
