Watson Mills and Roger Bullard suggest that during the Old Kingdom of Egypt, Byblos was virtually an Egyptian colony.
The growing city was evidently a wealthy one and seems to have been an ally (among "those who are on his waters") of Egypt for many centuries.
First Dynasty tombs used timbers from Byblos.
One of the oldest Egyptian words for an oceangoing boat was "Byblos ship".
 Archaeologists have recovered Egyptian-made artifacts as old as a vessel fragment bearing the name of the Second dynasty ruler Khasekhemwy, although this "may easily have reached Byblos through trade and/or at a later period".
Objects have been found at Byblos naming the 13th Dynasty Egyptian king Neferhotep I, and the rulers of Byblos maintained close relationships with the New Kingdom pharaohs of Ancient Egypt.

Around 1350 BC, the Amarna letters include 60 letters from Rib-Hadda and his successor Ili-Rapih who were rulers of Byblos, writing to the Egyptian government.
This is mainly due to Rib-Hadda's constant pleas for military assistance from Akhenaten.
They also deal with the conquest of neighboring city-states by the Habiru.

It appears Egyptian contact peaked during the 19th dynasty, only to decline during the 20th and 21st dynasties.
In addition, when the New Kingdom collapsed in the 11th century BC, Byblos ceased being a colony and became the foremost city of Phoenicia.
 Although the archaeological evidence seems to indicate a brief resurgence during the 22nd and 23rd dynasties, it is clear after the Third Intermediate Period the Egyptians started favoring Tyre and Sidon instead of Byblos.

Archaeological evidence at Byblos, particularly the five Byblian royal inscriptions dating back to around 1200–1000 BC, shows existence of a Phoenician alphabet of twenty-two characters; an important example is the Ahiram sarcophagus.
The use of the alphabet was spread by Phoenician merchants through their maritime trade into parts of North Africa and Europe.
One of the most important monuments of this period is the Temple of the Obelisks, dedicated to the Canaanite war god Resheph, but this had fallen into ruins by the time of Alexander the Great.
