Alma Viktoria Leontina Johansson (29 October 1880–31 December 1974) was a Swedish missionary who worked in the city of Mush in the Ottoman Empire at the beginning of the 20th century.

In 1901, the Missionary Society of Swedish women sent Johansson to Mush (Western Armenia), where she stayed until December 1915.

On the outbreak of World War I, the atrocities against the empire's Christian minorities escalated and she became an eyewitness to these crimes against humanity.

She gave information about how children at the orphanage were handed over to a Turkish officer, who then took them to a building outside the city where they all were executed.

The film "Map of Salvation" (2015) tells about Johansson and four European humanist women's lives and activities.
