Twic State is one of the states of South Sudan. It is located in the Bahr el Ghazal region and it borders Aweil East to the west, the disputed Abyei region to the north, Gogrial to the south, Northern Liech to the east, and Ruweng to the northeast. The capital of the state is Mayen-Abun.
On 2 October 2015, President Salva Kiir issued a decree establishing 28 states in place of the 10 constitutionally established states. The decree established the new states largely along ethnic lines. A number of opposition parties and civil society groups challenged the constitutionality of the decree. Kiir later resolved to take it to parliament for approval as a constitutional amendment. In November the South Sudanese parliament empowered President Kiir to create new states.
Twic state is made up of six counties created in February 2016. These counties were created by the governor of the state. These counties are Akoc County, Pannyok County, Wunrok County, Ajak County, Turalei County and Aweng County. Along with the creation of these counties, six county deputies have been appointed for each county.
Turalei is the state's capital. It is also the state's largest city, with over 2,000 residents. The issue of the capital became a major debate when Mayen Abun was decreed as the seat of state government from Turalei, the longtime capital of Twic County. However the state government promised to settle the issue amicably and consultative meetings have been undergoing on as the way forward to reach solution.
