{{Further|Filipino middle names}}

Middle names constitute the mother's maiden surname; is inserted between the given name and the surname (father's surname) and almost always abbreviated signifying that it is a "middle name". 

For example; given the name Jose Patricio Santos. This is usually abbreviated to Jose P. Santos. The abbreviated "P" signifies it is the maternal maiden surname.
If a person has two given names, Jonathan Jose P. Santos, the abbreviated "P" will represent the mother's surname. The given name would therefore be Jonathan Jose. The second name "Jose" is never classified as a middle name. There have been a few documented exceptions, such as [[Benigno Aquino III|Benigno S. Aquino III]], [[Jose P. Laurel]], and [[Manuel L. Quezon]], whose Western-style middle initials actually stand for their second given names Simeon, Paciano, and Luis respectively.
