The Maine Island Trail Association (abbreviated MITA) is a grassroots, volunteer-run conservation and preservation group based in Portland, Maine, United States.

The survey discovered around 1,300 unclaimed geographical features, including islands and sandbars.

[1] It also manages the Maine Island Trail, a recreational water trail which runs the entire coast of Maine,[2] connecting (as of 2023) 182 island and 76 mainland sites available for day visits or overnight camping.

[2][5][6] On private and state-owned properties, public access is provided in exchange for MITA's caretaking.

[10][11] MITA was co-founded by David R. Getchell Sr.,[7] a native of Bangor, Maine.
