Ixlu (Mayan pronunciation: [iʃˈluː]) is a small Maya archaeological site that dates to the Classic and Postclassic Periods.

Ixlu is approximately 28 km (17 mi) south of the ruins of the major Classic Period city of Tikal.

Archaeological investigations have uncovered potsherds dating as far back as the early Middle Preclassic (1000 BC–800 BC).

[6] The Petén Lakes region finally fell to the Spanish Crown in 1697,[7] at which time Ixlu was in disputed territory between the mutually hostile Itza and Kowoj kingdoms.

[10] The site possesses a twin pyramid complex, a feature that is rare outside of Tikal and probably indicates the political influence of that great city.

[14] A stairway ascended the west side of the temple and there was an altar on the summit that measured 1 metre (3.3 ft).

[20] The monuments of Ixlu bear some hieroglyphic texts that closely resemble texts from the site of Dos Pilas, suggesting that the lords of Ixlu may have been refugees from the collapse of that state in the Petexbatún region of the Petén Basin,[21] a state that itself professed to have a legitimate claim to the rulership of Tikal.
