Tortuguero, Maya archaeological site in Macuspana, Mexico.

Tortuguero is an ancient Maya site in Macuspana featuring limestone structures and monuments built across a strategic location. These remains stand between the Tabasco highlands and the flat plains of the Gulf Coast region.

During the Classic Period between 600 and 900 CE, Tortuguero was linked to the city of Palenque and shared the same dynastic emblem. The two places formed a defensive alliance in this region of Mexico.

The site's modern name comes from El Tortuguero hill, but Monument 6 names the city B'aaku'l'. Its glyphs describe Bahlam Ajaw's 644 CE star war, commemorated with the line "the blood was pooled, the skulls were piled", and the descent of Bolon Yokte' K'uh at the close of the 13th bak'tun on 21 December 2012.

Tortuguero is not open to the public. It lies 50 km from Villahermosa and 10 km from Macuspana, on the slopes of El Tortuguero hill. The site is known from four plans made between 1918 and 1978, which record up to seven buildings.

A cement factory was built directly over the site in the 1960s, causing substantial damage to the ancient Maya structures buried beneath. This industrial installation now covers the ancient ground, making it difficult to access for archaeological work.
