Our Natural History collection contains over 250,000 specimens of local, national and worldwide origin. This includes thousands of specimens collected in the 19th century as part of the original Horniman bequest. Many thousands more specimens were added to the collection throughout the 20th and early 21st centuries for the purpose of education, display, reference and research.

Our collection is varied and contains a range of biological and geological material and its associated data. We have taxidermy cases and mounts, study skins, whole skeletons and bones, dried pressed plants, fungi, mollusc shells, birds' eggs, pinned insects, histological slides, models, fluid preserved material, fossils, minerals and rocks. Some parts of the collection also contain detailed associated field notebooks, photographs and other archival information, including those of Hampshire taxidermist and wildfowler Edward Hart.

Due to its age, our collection includes examples of rare fossils and animals collected from many parts of the world. We also hold a number of type specimens associated with the collections of Frederick Horniman and Dr J. P. Brock. Today our collections are researched, developed and used to encourage a deeper understanding, appreciation and enjoyment of the natural world. Some of our more notable collections are listed below.
