布氏中喙鲸或柏氏中喙鲸（学名Mesoplodon densirostris），旧称布兰氏喙鲸，也名钝喙鲸，大西洋喙鲸，热带喙鲸和瘤齿喙鲸，似乎是中喙鲸属中分布最广泛的物种，也是本属唯一已有确实海中观测研究数据者。已知经常传出目击记录的地点至少有三处：夏威夷欧胡岛外海、南太平洋社会群岛外海、与巴哈马东北部。其种名源自拉丁文的densus（意为「厚」或「密」）与rostrum（意为「嘴喙」）。

Blainville's beaked whale (Mesoplodon densirostris), or the dense-beaked whale, is the widest ranging mesoplodont whale and perhaps the most documented. The French zoologist Henri de Blainville first described the species in 1817 from a small piece of jaw — the heaviest bone he had ever come across — which resulted in the name densirostris (Latin for "dense beak"). Off the northeastern Bahamas, the animals are particularly well documented, and a photo identification project started sometime after 2002.
