Lugal-dalu (Sumerian: 𒈗𒁕𒇻) was a Sumerian ruler of the Mesopotamian city of Adab in the mid-3rd millennium BCE, probably c. 2500 BCE.

[1] His name does not appear in the Sumerian King List, but he is known from one of a statue bearing his name.

The statue is similar in style to those of other Sumerian kings such as Meannesi or Entemena, sons of En-anna-tum I.

[5] The inscription in archaic cuneiform on the statue reads 𒂍𒊬 𒈗𒁕𒇻 𒈗𒌓𒉣𒆠 è-sar lugal-dalu lugal adab-(ki) "In the temple Esar, Lugaldalu king of Adab", referring to the Esarra Temple in Adab.
