%X The giraffe (Giraffa camelopardalis) is both the largest extant ruminant and a strict browser. We dissect and describe the macroscopic anatomy of the mouth of the giraffe. The heads of two adult giraffes and one fetus were used in this study. The lips were well developed, the upper one was predominant and dorsally flattened near the nostrils. The tongue had a lift or lingual torus and rostrally to it a groove-shaped depression or fossa linguae. There was no adipose body of cheek (Corpus adiposum buccae). The hard palate in the giraffe had 18 Rugae palatinae. The final roughness reaches the caudal border of the premolar 3. Caudal ridges had no papillae. The parotid gland was small and consisted of two lobes, one rostral and one caudal to be separated dorsally to accommodate the parotid lymph node. The parotid duct followed the same way as in the cow, ended in front of the upper premolar tooth 2 in the parotid papilla, (not evident at mucosal surface). Mandibular gland was divided into two lobes, the rostral one placed in the intermandibular space and the caudal hidden by the parotid gland. Giraffes have the monostomatic and polistomatic sublingual glands. The monostomatic sublingual gland was located rostrally and joined to the monostomatic of the other side in the very narrow rostral intermandibular space. The polistomatic sublingual gland was caudally located and reached the level of the third molar and at a deeper level than the monostomatic. The studied giraffes had dorsal, ventral and intermediate bucal salivary glands. Leaving aside the differences caused by different dimensions, the mouth of the giraffe had in general a similar anatomical arrangement to the cow. La jirafa (Giraffa camelopardalis) es a la vez el rumiante m¨¢s grande que existe y un ramoneador estricto. Nosotros disecamos y describimos la anatom¨ªa macrosc¨®pica de la boca de la jirafa. En este estudio se utilizaron las cabezas de dos jirafas adultas y de un feto. Los labios estaban bien desarrollados, el superior era el predominante y estaba aplastado dorsalmente cerca de las narinas. La lengua ten¨ªa una protuberancia o Torus lingual y rostralmente a ¨¦l una depresi¨®n en forma de surco o Fossa linguae. No hab¨ªa cuerpo adiposo de la mejilla (Corpus adiposum buccae). El paladar duro en la jirafa ten¨ªa 18 rugae palatinae. Las rugosidades finales alcanzaban el borde caudal del premolar 3. Las crestas caudales no ten¨ªan papilas. La gl¨¢ndula par¨®tida era peque a y consist¨ªa de dos l¨®bulos, uno rostral y otro caudal que se separaban dorsalmente para acomodar al n¨®dulo linf¨¢tico parot¨ªdeo. El c
