Robina Nicol (née Sinclair; 7 June 1861 – 17 July 1942) was a New Zealand photographer and suffragist.

Nicol née Sinclair was born on 7 June 1861 in Shetland, Scotland.

In 1885 she married Alexander Scott Nicol in Wellington, New Zealand.

Although considered an "amateur" because she did not pursue a career in photography, she was active in a time when there were few women photographers in New Zealand.

Her photographs were digitised by the Alexander Turnbull Library.
