The 2018 Olt County referendum was a referendum held in the Olt County in Romania to rename it to the "Olt-Romanați County" in 6 and 7 October 2018. This referendum was demanded by the inhabitants of the former Romanați County, especially those of its former capital Caracal, as they said it was to defend their identity and to remember the abolished county. The referendum did not attempt to enforce any administrative changes, only changes in the county's name. For it to pass, the voter turnout had to be of 30% or more out of the approximately 300,000 people eligible to vote in the Olt County at the time and the results had to be of 50%+1 votes or more saying "yes".
