Maat or Ma'at (Egyptian mˤ3t) was the ancient Egyptian concept of truth, balance, order, harmony, law, morality, and justice. Maat was also personified as a goddess regulating the stars, seasons, and the actions of both mortals and the deities, who set the order of the universe from chaos at the moment of creation. Her ideological counterpart was Isfet.

Cuneiform texts indicate that the word mˤ3t was pronounced /múʕʔa/ during the New Kingdom period, having lost the feminine ending t. Sound shifts from u to e later produced the cognate Coptic word ⲙⲉⲉ/ⲙⲉ "truth, justice".

The earliest surviving records indicating that Maat is the norm for nature and society, in this world and the next, were recorded during the Old Kingdom, the earliest substantial surviving examples being found in the Pyramid Texts of Unas (ca. 2375 BCE and 2345 BCE).

Later, as a goddess in other traditions of the Egyptian pantheon, where most goddesses were paired with a male aspect, her masculine counterpart was Thoth, as their attributes are similar. In other accounts, Thoth was paired off with Seshat, goddess of writing and measure, who is a lesser known deity.

After her role in creation and continuously preventing the universe from returning to chaos, her primary role in Egyptian mythology dealt with the weighing of souls (also called the weighing of the heart) that took place in the underworld, Duat. Her feather was the measure that determined whether the souls (considered to reside in the heart) of the departed would reach the paradise of afterlife successfully.
