Nicholas Edward Brown (11 July 1849 in Redhill, Surrey – 25 November 1934 in Kew Gardens, London) was an English plant taxonomist and authority on succulents.

He produced many annotated drawings of succulent plants in his work revising the genus Mesembryanthemum, which were published in 1931.

The Araceae genus Nebrownia was named in his honour by Otto Kuntze.

[2] The plant Anthurium brownii and the genus Brownanthus (now a synonym of Mesembryanthemum) also bear his name.

He was awarded the Captain Scott Memorial Medal by the South African Biological Society in recognition of his work on SA flora, and in 1932 an honorary D.Sc.
