# Sub-national opinion polling for the 2008 Spanish general election

In the run up to the 2008 Spanish general election, various organisations carried out opinion polling to gauge voting intention in autonomous communities and constituencies in Spain during the term of the 8th Cortes Generales. Results of such polls are displayed in this article. The date range for these opinion polls is from the previous general election, held on 14 March 2004, to the day the next election was held, on 9 March 2008.
Voting intention estimates refer mainly to a hypothetical Congress of Deputies election. Polls are listed in reverse chronological order, showing the most recent first and using the dates when the survey fieldwork was done, as opposed to the date of publication. Where the fieldwork dates are unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour. If a tie ensues, this is applied to the figures with the highest percentages. The "Lead" columns on the right shows the percentage-point difference between the parties with the highest percentages in a given poll.
Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between polling organisations. When available, seat projections are displayed below the percentages in a smaller font.
