The Republican statewide nominating convention was held May 11–12, 2018 at Foxwoods Resort Casino in Ledyard, Connecticut.

Under the rules established by the convention, any candidate not receiving at least eight percent of the vote would be eliminated in the first round of voting. In the second round of voting, candidates not receiving 15 percent of the vote would be eliminated. In all subsequent rounds of voting, the candidate with the fewest votes would be eliminated, regardless of percentage. Voting would continue until one candidate receives 50 percent plus one of all votes cast.{{cite web|url=http://ct.gop/wp-content/uploads/sites/23/2018/05/2018-Rules.docx|title=2018 GOP Convention Rules|access-date=May 14, 2018|archive-date=May 15, 2018|archive-url=https://web.archive.org/web/20180515043655/http://ct.gop/wp-content/uploads/sites/23/2018/05/2018-Rules.docx|url-status=dead}}
