Abdul Ghaffar (Arabic: عبد الغفار) and Abdul Ghafoor (Arabic: عبد الغفور) are two related male Muslim given names, and, in modern usage, surnames. They are built from the Arabic words Abd, al- and either Ghaffar or Ghafoor respectively. Both names mean "servant of the All-forgiving", Al-Ghaffār and Al-Ghafūr being two of the names of God in the Qur'an, which give rise to the Muslim theophoric names.
The letter a of the al- is unstressed, and can be transliterated by almost any vowel, often by u. Alternative transliterations for the last word allow for the initial "gh" to appear as "g", the "ff" to appear as "f" or vice versa, and the "oo" to appear as "u" or "ou", all subject to variable spacing and hyphenation.
