A by-election for the Zlín Senate seat in the Czech Republic was held on 18 and 19 May 2018 as a result of František Čuba's resignation.

[4][5][6][7] František Čuba was elected Senator in 2014 as a candidate of the Party of Civic Rights.

ANO 2011 had its candidate chosen at the time of Čuba's resignation but refused to announce his name.

Michaela Blahová was speculated as a candidate of the Christian and Democratic Union – Czechoslovak People's Party.

[10] Czech Pirate Party decided to find a candidate by publishing an advertisement in local media.

He stated he wants to prove that Senate is an important part of Czech Constitutional system.

Miroslav Adámek was nominated by Mayors and Independents and supported by the Civic Democratic Party and TOP 09.

He published a video spot that received mixed responses and had 15 billboards set up.

[18] Michaela Blahová stated that her success might be caused by the fact that she was the only female candidate in the election.

[14] Communist Party candidate Rafaja admitted he is disappointed with the result as he expected that he could advance to the second round.

First preliminary results showed candidates tied but Goláň started leading when more votes were counted.

[24] Goláň thanked Blahová for a correct campaign and stated he plans to focus on taxes and opposition to privatisation of some vital resources, including water.

She considered her result as a success because no candidate of KDU-ČSL advanced to the second round in previous elections.
