The New Kingdom, also called the Egyptian Empire, refers to ancient Egypt between the 16th century BC and the 11th century BC. This period of ancient Egyptian history covers the Eighteenth, Nineteenth, and Twentieth dynasties. Through radiocarbon dating, the establishment of the New Kingdom has been placed between 1570 and 1544 BC. The New Kingdom followed the Second Intermediate Period and was succeeded by the Third Intermediate Period. It was the most prosperous time for ancient Egypt and marked the peak of its power.

In 1845, the concept of a "New Kingdom" as one of three "golden ages" was coined by German scholar Christian Charles Josias von Bunsen; the original definition would evolve significantly throughout the 19th and 20th centuries. The later part of this period, under the Nineteenth Dynasty (1295–1189 BC) and the Twentieth Dynasty (1189–1069 BC), is also known as the Ramesside period. It is named after the eleven pharaohs who took the name Ramesses, after Ramesses I, who founded the Nineteenth Dynasty, and his grandson Ramesses II, who was its longest-reigning monarch.

Possibly as a result of the foreign rule of the Hyksos during the Second Intermediate Period, the New Kingdom saw a historic expansion into the Levant, thus marking Egypt's greatest territorial extent. Similarly, in response to attacks by the Kushites, who led raids into Egypt during the Second Intermediate Period, the rulers of the New Kingdom felt compelled to expand far into Nubia and to hold wider territories in the Near East, particularly on the Levantine frontier.

The Eighteenth Dynasty included some of Egypt's most famous kings, including Ahmose I, Hatshepsut, Thutmose III, Amenhotep III, Akhenaten, and Tutankhamun.

Ahmose I is viewed to be the founder of the eighteenth dynasty. He continued the campaigns of his father Seqenenre Tao and of Kamose against the Hyksos until he reunified the country once more. Ahmose would then continue to campaign in the Levant, the home of the Hyksos, to prevent any future invasions on Egypt.

Ahmose was followed by Amenhotep I, who campaigned in Nubia and was followed by Thutmose I. Thutmose I campaigned in the Levant and reached as far as the Euphrates, thus becoming the first pharaoh to cross the river. During this campaign, the Syrian princes declared allegiance to Thutmose. However, after he returned, they discontinued tribute and began fortifying against future incursions.

Hatshepsut was one of the most powerful pharaohs of this dynasty. She was the daughter of Thutmose I and the royal wife of Thutmose II. Upon the death of her husband, she ruled jointly with his son by a minor wife, Thutmose III, who had ascended to the throne as a child of about two years of age, but eventually she ruled in her own right as king. Hatshepsut built extensively in the Karnak temple in Luxor and throughout all of Egypt and she re-established the trade networks that had been disrupted during the Hyksos rule of Lower Egypt during the Second Intermediate Period, thereby building the wealth of the Eighteenth Dynasty. She oversaw the preparations and funding for a mission to the Land of Punt. After her death, having gained valuable experience heading up the military for Hatshepsut, Thutmose III assumed rule.

Thutmose III expanded Egypt's army and wielded it with great success to consolidate the empire created by his predecessors. This resulted in a peak in Egypt's power and wealth during the reign of Amenhotep III. The term pharaoh, originally the name of the king's palace, became a form of address for the person who was king during his reign (c. 1479–1425 BC).
