Iliwerung or Illiwerung is a complex volcano forming a prominent south-facing peninsula on Lembata Island in southern Indonesia.

[2] Eruptions since 1973 have been confined to Hobal, a submarine parasitic vent on Iliwerung's lower east-southeastern flank.

[1][2] Iliwerung lies on the southern rim of the Lerek caldera.
