Expo 2027 (Serbian: ЕКСПО 2027 / EKSPO 2027) is the working title for a BIE recognised specialised exposition to be held in 2027 in Belgrade, Serbia. It is scheduled to begin on 15 May 2027 and close on 15 August 2027. This will be the first world exposition to be held in the former Yugoslavia.

Five countries submitted competing candidatures to organise a Specialised Expo in either 2027 or 2028: the United States of America (in Minnesota), Thailand (in Phuket), Serbia (in Belgrade), Spain (in Malaga), and Argentina (in San Carlos de Bariloche).

The candidature list closed on 28 January 2022. Each candidate submitted a detailed candidature dossier by 7 June 2022, and the BIE then organised Enquiry Missions, assessing the feasibility and viability of each candidature project. Serbia was elected as the host country of Specialised Expo 2027/28 by BIE Member States, gathered in the 172nd General Assembly which took place on 21 June 2023.

Minnesota had previously bid for Expo 2023 with Healthy People, Healthy Planet: Wellness and Well Being for All.

The theme for this bid for 2027 was Healthy People, Healthy Planet and would have been held in Bloomington, Minnesota adjacent to the Mall of America and the Minnesota Valley National Wildlife Refuge, and close to Minneapolis-St. Paul International Airport. The expected number of visitors was 13.3 million.

Minnesota was the first to formally submit their bid on 29 July 2021. A group of BIE officials visited the site in October 2022 to hear presentations that included renderings of proposed structures designed by DLR Group for the expo. This would have been the first World Fair to be held in the Western Hemisphere since Expo 86.

The theme for this bid for 2028 was Future of Life: Living in Harmony, Sharing Prosperity.

The theme of this winning bid for 2027 is Play for Humanity – Sport and Music for All.
