银杏齿中喙鲸（学名Mesoplodon ginkgodens）旧称银杏齿喙鲸，又称日本喙鲸和银杏喙鲸。仅在1958年有过正式的描述报告，在本就罕为人知的喙鲸科中更是数据极少的几个物种之一，虽然日本沿岸的捕鲸者在猎捕柯氏喙鲸时曾捕获少量的银杏齿中喙鲸与其他种喙鲸（多为胡氏中喙鲸）。为此种中喙鲸命名的日本科学家指出，牠们的牙齿形似银杏的叶子，俗名即由此而来。科学家曾检验少数捕鲸者捕获的个体，但关于银杏齿中喙鲸的大部分研究数据仍取自搁浅尸体。

The ginkgo-toothed beaked whale (Mesoplodon ginkgodens) is a poorly known species of whale even for a beaked whale, and was named for the unusual shape of its dual teeth. It is a fairly typical-looking species, but is notable for the males not having any scarring.
