The 30 venues have been chosen based on their performances over the last 12 months in the event industry.
Competition was tough as many of the shortlisted venues were heavily involved in the Olympics, while others simply posted record revenue figures and hosted more events than ever before.
The Event editorial team has spoken but now it is up to you, the readers, to decide who makes into the final 20, and who walks away with the Top 20 Venues poll coveted crown.
Last year The O2 took the number one spot, but who will it be this year? You can decide by voting here.
The deadline for voting is Wednesday 17 October.
The results of the poll will be revealed in the November//December print issue of Event magazine, which can be ordered here.
