Elsie Mary Griffin (1 November 1884 – 3 May 1968) was a New Zealand botany teacher and community organisation administrator.
Elsie Griffin had attended the Methodist Prince Albert College in Queen Street, Auckland, and in 1906 she was awarded an MA with honours in botany from Auckland University College.
In that year she took up a position as the botany mistress at Auckland Girls' Grammar School.
Elsie Griffin took her pupils on long hikes in the Waitākere Ranges so that they could collect specimens.
She was the secretary of the YWCA in Dunedin from 1912 to 1915, and it was this experience that led her to spend the next two years studying social work methods in America.
