Haapi, also Haip and Ha'ip was a commissioner of the 1350–1335 BC Amarna letters correspondence. The name "Hapi" in Egyptian is the name for the Nile god Hapi. Haapi is referenced in 3 letters from the Byblos-(Gubla) corpus of the prolific writer Rib-Hadda, of 68 letters. Haapi is also referenced in letter EA 149 of Abimilku of Tyre-(Surru), (EA for 'el Amarna'). The following letters are referenced to Haapi/Ha'ip:

The letters of commissioner: Haapi/Ha'ip

EA 149, "Neither water nor wood", letter no. 4 of 10

Letter no. 4 of 10 by Abimilku of Tyre. (Abimilku points out to Pharaoh, that Pharaoh is still communicating with Aziru, by tablet-letter.)

EA 132, "The hope for peace"

Rib-Hadda letter; see Egyptian commissioner: Pahura.

EA 107, "Charioteers, but no horses"

See also Maryannu; in letter: mar-i(y)a-nu-ma, =charioteer. EA 107 is a virtually undamaged tablet-letter. 107 also shows the precise spelling of the term: charioteer/Maryannu. The 'matters'/'discussions', (i.e. the topic), of this letter appears to be twofold: 1) Ha'ip justification, or appropriateness as a commissioner, and 2) the events in Damascus/Dimašqu with the warring Aziru.
