Mahone Islands Conservation Association (MICA) is a not-for-profit organization dedicated to the conservation of islands and shoreline of Mahone Bay, Nova Scotia, Canada.

The association was formed in reaction to private development of the area's islands which displaces nesting seabirds and threatens to spoil the landscape.

Under a stewardship agreement, islands are managed jointly by MICA and the province of Nova Scotia.

MICA receives funding from the Province of Nova Scotia and about 40 corporate sponsors, as well as local fundraising.
