Daegu Stadium, known as the Blue Arc, is a multi-purpose stadium in the Suseong District of Daegu, South Korea, with a seating capacity of 66,422. Its roof consists of two inclined steel truss arches, each spanning 273 m with a rise of only 28.7 m, propped by 13 secondary arches and covered by a PTFE-coated glass-reinforced fabric canopy. The total roof steel weighs 4,350 t, and the field has natural grass with a Mondotrack running track.

Construction began on 29 July 1997 and the stadium opened on 28 June 2001, built for the 2002 FIFA World Cup and the 2003 Summer Universiade at a cost of USD 265 million. It was first called Daegu Sports Complex, renamed Daegu World Cup Stadium on 20 March 2002, and took its current name on 5 March 2008. It hosted the 2003 Universiade and the 2011 World Championships in Athletics, and was Daegu FC's home from 2003 to 2018.

The stadium hosts the Daegu Marathon every April and has staged the 8th Asia Song Festival in 2011 and the Vector EDM Festival in May and October 2022. Since 2019 it has served as the home ground of Daegu FC B, after the first team moved to DGB Daegu Bank Park.

The venue offers ample parking and is accessible by public transportation. Visitors should allow extra time when attending major events, as traffic can become congested during popular matches.

The roof's two inclined steel arches each span 273 m but rise only 28.7 m, giving the stadium its "Blue Arc" nickname. The total roof steel weighs 4,350 t, and the canopy is a PTFE-coated glass-reinforced fabric. Wind-tunnel studies by BMT Limited assessed the roof's wind loading.
