Ruthie and Connie LGBT Elder Americans Act of 2015

Amends the Older Americans Act of 1965 to include LGBT individuals (lesbian, gay, bisexual, and transgendered individuals) within the purview of such Act, particularly their status as LGBT individuals among those with the greatest social need.

Authorizes the Administration of Aging to: (1) designate within it a person with responsibility for addressing issues affecting LGBT older individuals; (2) conduct studies and collect data to determine the services needed by LGBT older individuals; and (3) establish and operate the National Resource Center on Lesbian, Gay, Bisexual, and Transgendered Aging.

Revises the list of activities of national significance for families and other caregivers, for which the Administration's grants may be used, to specify those provided to individuals with greatest social need which: (1) address physical and mental health, disabilities, and health disparities; (2) provide long-term care, including in-home and community-based care; (3) provide informal care and formal care in a facility setting; (4) provide access to culturally responsive health and human services; and (5) address other gaps in assistance and issues of particular importance to older individuals with the greatest social need.

Requires a State Long-Term Care Ombudsman to collect and analyze discrimination data with respect to LGBT older individuals in the admission to, transfer or discharge from, or lack of adequate care provided in long-term care settings.
