Dame Elizabeth May Gilmer DBE FRHortS (née Seddon; 24 March 1880 – 29 February 1960) was a New Zealand social worker, educationist and horticulturist.

[1] Throughout her life she was involved in a staggering array of welfare and women's organisations in addition to her most abiding interests which were conservation and horticulture.

[2] In 1941, she was elected to the Wellington City Council, where she served 12 years as chair of both the Libraries and Parks and Reserves Committees.

Gilmer’s own colleagues in the Citizens' Association backed Stevens in preference to her, though she received the support of the Labour Party councillors.

Dropped from the Citizens' Association ticket in 1953, she accepted the request of a public deputation to stand for re-election as an independent, but lost her seat on the council.
