Opinion polling for the 2011 Croatian parliamentary election

Opinion polling for the 2011 Croatian parliamentary election started early after the previous election with polls on individual parties. As electoral coalitions were formed, coalition ratings started to be polled as well. The poll results below are listed by category and ordered in reverse chronological order. Major political events are indicated chronologically between individual polls. Concurrent polling was at the time also done for the 2012 Croatian European Union membership referendum.

Seat projections
The three main national television stations contracted Ipsos Puls to conduct exit polling at 403 stations.

Overall party rating
Generic national polls are conducted to indicate overall party rating and provide a trend indicator, while the actual election is conducted not with a single electoral unit but with the Croatian Parliament electoral districts.



The listed poll dates are either the dates when the poll was conducted, or alternatively the date when the poll result was published.

Seat projections
Because the seats in the Parliament are split according to Croatian Parliament electoral districts, seat projections significantly vary from a generic overall poll.

The seat projections do not include: The new composition of Parliament will have 151 seats meaning that 76 seats will be needed for a majority.
 * the 8 seats from minority voters, and these representatives are not usually strictly aligned with mainstream parties
 * the 3 seats from voters residing abroad, which have in every election since independence gone to HDZ

Because of the nature of the D'Hondt method and the division into constituencies, seat projections are less reliable, so some polls list tentative options, indicated in parentheses.
