Harry Wallis Kew FZS (1868–1948) was an amateur English zoologist.

Wallis Kew worked as a bank clerk in Kent and devoted his free time to the study of pseudoscorpions and molluscs.

[1] He is best remembered for his book entitled The dispersal of shells; an inquiry into the means of dispersal possessed by fresh-water and land Mollusc, which included a preface by Alfred Russel Wallace.

In this work, Wallis Kew was tracking the phenomena that is now referred to as invasive species in relation to molluscs,[2] and in particular the zebra mussel.

[5] The gastropod Ameranella kewi (Dickerson, 1915) was named in his honour.
