Ek Balam is an ancient Mayan archaeological site located in the Yucatán Peninsula, Mexico. It is situated approximately 40 km (25 miles) north of Valladolid and 85 km (53 miles) west of Cancún. The site is well known for its well-preserved ruins, including a large acropolis that dates back to the late Pre-Classic period (300 BC-300 AD).

The name Ek Balam means "Black Jaguar" in the Mayan language and refers to the jaguar-shaped reliefs that are carved into the walls of the acropolis. The acropolis is the main attraction at Ek Balam and consists of a large central plaza surrounded by buildings and pyramids. The tallest of these pyramids, known as the "El Rey" (The King) pyramid, stands at an impressive 38 meters (125 feet) tall. Visitors can climb to the top of the pyramid for a panoramic view of the site and the surrounding jungle.

In addition to the acropolis, Ek Balam also features several other structures and buildings, including a ball court, residential buildings, and several smaller pyramids. Many of these structures are well preserved, with intricate carvings and detailed stucco work still visible.
