ReDrawing Edinburgh was a community-led outreach project marking the centennial commemoration of the 1920 Edinburgh Boundaries Extension and Tramways Act.

The Act saw the city boundaries extended to incorporate the Burgh of Leith in the north and the Midlothian parishes of Colinton, Corstorphine, Cramond and Liberton to the west and south of the city. The expansion meant the city grew from 17 square miles to 53 square miles and increased its population from 320,000 to 425,000.

Activities to commemorate the anniversary were coordinated by a community steering group comprising representatives from each of the boundary extension areas, with support from Archives, Library, and Museum services.
