Miroslav Sládek (24 October 1950 in Hradec Králové) is a Czech politician, and the founder and chairman of the right-wing populist Rally for the Republic – Republican Party of Czechoslovakia (SPR-RSČ).

Sládek was the most prominent and active member of the party, visiting several towns or villages each day to make political speeches.

Their policy programme focused on issues such as corruption during voucher privatisation and crime among Roma communities, and promised to solve them with an "iron fist".

In 2006 he was sentenced to a fine because of the debt accumulated by SPR-RSČ, and was forbidden to run for the leadership of any political party for three years.

[1] In one interview Sládek expressed the view that while he had personally failed, the whole political scene had nonetheless become "Sládek-like" in the meantime.

He is married to Laura Sládková, who was also involved in leadership positions in the Coalition for Republic – Republican Party of Czechoslovakia.
