Australian interior designer Miriam Fanning is the founder and principal of Mim Design.

Fanning's studio, which celebrated its twentieth anniversary in 2021, works across a range of design projects from high-end single and multi-residential homes through to hospitality, hotel, showrooms and large-scale retail. Recent projects include a cafe and bar conceived as a "greenhouse sanctuary" in Melbourne, as well as a light-filled open-plan office renovation also in the city.

Fanning regularly headlines speaking engagements and panels, actively advocates for the Design Institute of Australia and mentors emerging designers. In recognition of her industry contributions, Fanning was awarded the prestigious IDEA 'Gold Medal' in 2025.
