Dragutin Lesar (born 4 March 1956) is a Croatian politician. Originally a union leader in the 1980s, he joined the liberal Croatian People's Party (HNS) in 1996. As member of HNS he was elected to the Croatian Parliament in the 2003 and 2007 general elections and served in the 5th and 6th Sabor. In April 2008 he resigned from HNS and continued to serve in the parliament as an independent. In April 2010 he founded the left wing Croatian Labourists – Labour Party (HL) and became their first party president.
In autumn of 1996, he contacted Radimir Čačić, Srećko Bijelić, Savka Dabčević-Kučar and Dragutin Haramija and joined Croatian People's Party (HNS), and few months later he became the party's vice-president and worked so in the party for next 12 years. During the local elections in 1997 he was holder of the list for Međimurje County and candidate for House of Counties of Croatian Sabor. His rivals were Franjo Tuđman, Ivica Račan, Vlado Gotovac and Drago Stipac. He won 14.66% of votes and thus he did not enter the Sabor, but he did succeed in winning 5 seats for County Assembly and made a coalition with Croatian Social Liberal Party and Croatian Peasant Party and thus removed Croatian Democratic Union from ruling role. Lesar became prefect's deputy. During 2000, Međimurje County Assembly accepts Lesar's proposal for foundation of Međimurje solidarity foundation "Katruža", and he becomes the manager of the foundation. On local elections in 2001 he won 6 seats and formed the same coalition and again becomes prefect's deputy.
During the Croatian parliamentary elections of 2003, Lesar was the top-ranked candidate of the electoral list of HNS for the 3rd Electoral District. HNS won 2 seats, so Lesar entered in Sabor along with Radimir Čačić. During the parliamentary elections of 2007 he again became member of the parliament, but due to conflict with newly elected president of the HNS Radimir Čačić, he left HNS and acted as independent member of parliament since April 2008.
On 31 March 2010 Lesar founded Croatian Labourists – Labour Party and became its president. He competed in the Croatian parliamentary election, 2011 and won a seat in parliament.
