Girsu (Sumerian Ĝirsu;[1] cuneiform ĝir2-suki 𒄈𒋢𒆠) was a city of ancient Sumer, situated some 25 km (16 mi) northwest of Lagash, at the site of what is now Tell Telloh in Dhi Qar Governorate, Iraq.

As the religious center of the kingdom of Lagash, it contained significant temples to the god Ningirsu (E-ninnu) and his wife Bau and hosted multi-day festivals in their honor.

Telloh was the first Sumerian site to be extensively excavated, at first under the French vice-consul at Basra, Ernest de Sarzec, in eleven campaigns between 1877 and 1900, followed by his successor Gaston Cros from 1903–1909.

[6][7][8][9] Finds included an alabaster statue of a woman, with copper bracelets coated in gold and a fragment of a stone lion carved dish with a partial Sumerian inscription.

[21][22] In March 2020, archaeologists announced the discovery of a 5,000-year-old cultic area filled with more than 300 broken ceremonial ceramic cups, bowls, jars, animal sacrifices, and ritual processions dedicated to Ningirsu.
