Menpehtyre Ramesses I (traditional English: Ramesses or Ramses) is the founding Pharaoh of Ancient Egypt's 19th dynasty.

The dates for his short reign are not completely known but the timeline of late 1292-1290 BCE is frequently cited as well as 1295-1294 BCE.

While Ramesses I is the founder of the 19th Dynasty, in reality his brief reign marks the transition between the reign of Horemheb who had stabilized Egypt in the late 18th dynasty and the rule of the powerful Pharaohs of this dynasty, in particular his son Seti I and grandson Ramesses II, who will bring Egypt up to new heights of imperial power.
