Triumfetta rhomboidea, commonly known as diamond burbark, Chinese bur, or kulutkulutan in Tagalog, is a shrub that is extensively naturalised in tropical regions. It is thought that to have come to Australia from China. Its bark—sometimes called burbark—makes a kind of jute.

The taxon was first formally described in 1760 by botanist Nikolaus von Jacquin.
