Isabella Gordon OBE FZS FLS (18 May 1901 – 11 May 1988) was a Scottish marine biologist who specialised in carcinology and was an expert in crabs and sea spiders.

[4] In 1937 the Crustacea section was split into two parts; J.P. Harding took over entomostraca while Gordon managed malacostraca as Principal Scientific Officer.

In April 1961 on the occasion of Emperor Hirohito's 60th birthday, Gordon was invited to spend several weeks in Japan under the sponsorship of the Japanese newspaper Yomiuri Shimbun.

On 5 April she was invited to the laboratories of the Imperial Household where she had an informal audience with the Emperor, a keen marine biologist himself.

The visit gave Gordon great pleasure and she retained contact with her Japanese colleagues for the rest of her life.

In 1958 she published a review of Siewing's 'Anatomie und Histologie von Thermosbaena mirabilis' under the title 'A thermophilous shrimp from Tunisia'.
