{{TopicTOC-Biology}}
This is a '''list of [[Notability in the English Wikipedia|notable]] [[biologist]]s''' with a biography in Wikipedia. It includes [[zoologist]]s, [[botany|botanists]], [[biochemist]]s, [[ornithology|ornithologists]], [[entomology|entomologists]], [[Malacology|malacologists]], and [[Outline of biology|other specialities]].

<!-- Do not add names, unless there is also a biography available. -->
<!-- For the sake of consistency please use the following format: -->
<!-- [[Name]] (birth–death), Nationality speciality, a few words about why the person is notable -->
<!-- Also, if the title of the article also has the profession in parenthesis (e.g. [[James Bond (ornithologist)]]) use a pipe (|) after the parenthesis to ensure that the profession doesn't show up in the link (e.g. [[James Bond (ornithologist)|James Bond]]) 
athel_cb (20.09.2020): Since I started studying this list in the past few days (since 15th September 2020, therefore), I have noticed that the recommendations above are widely ignored, at least in part. "a few words" doesn't mean just one word, and it certainly doesn't mean no words. It's probably best to avoid have entries spread over multiple lines, but if they are kept to no more than 80 characters that still allows a useful amount of information on one line. A description such as "American biologist" contains just one piece of information, "American", because "biologist" can be assumed if the person is in a list of biologists.
