Adeline Paulina Irby (19 December 1831 – 15 September 1911) was a British travel writer and suffragist who founded an early girls' school in Sarajevo and organized relief to thousands of refugees.

Irby set out with her Scottish companion Georgina Muir Mackenzie initially to visit spa towns in Austria-Hungary and Germany in 1857.

[3] In 1858 they were arrested as spies in Starý Smokovec, a spa town in the Carpathian Mountains, on the grounds that they had "pan-Slavistic tendencies".

They were particularly concerned by the plight of Serbian Orthodox women and girls who found they had poor access to positions and schooling.

[2] In 1862 they published Notes on the South Slavonic Countries in Austria and Turkey in Europe based on Mackenzie's lecture in Bath and Across the Carpathians but they did this anonymously.

[6] Their requests for money were very successful and they opened a Christian school in Sarajevo staffed by German Protestant Deaconesses.

[10] For a number of years, an annual ceremony was held at her grave to mark the shot that initiated the First World War and there was belated commemorations of the centenary of her birth (in 1934) throughout Yugoslavia.
