Saint-Inglevert (; ) is a commune in the Pas-de-Calais department in the Hauts-de-France region of France.
The etymology of Saint-Inglevert, first attested as Sontingeveld in 1140, is now generally agreed to derive from a Common Germanic anthroponym *Sondo, followed by -ingen "people of" (see nearby e.g. Tardinghen) + -veld "field". The name was no longer understood sometime in the late Early Middle Ages, leading to a popular re-interpretation of the first syllable, "sant-ingheveld". This led to a folk etymology of prefixed saint (as is very common in toponymy across France), thus shaping Saint Inglevert. Thus the meaning is, "the field of the people of Sondo".
Despite old local veneration, if there ever truly was a "Saint Inglevert" which perhaps influenced the name, the holy figure is unknown and lost to time.
Saint-Inglevert is situated some north of Boulogne, at the junction of the D244 road with the A16 autoroute.
