No, SE doesn't organize community meetings themselves. Sometimes they do attend a conference about a specific subject, but the community isn't part of that.
Sometimes a community does organize a meeting, like Memor-X commented, Arqade and Manga do sometimes.
You are free to organize something yourself. There are no dedicated sites or pages to do this. You can use a chat room to find support for your meeting and maybe bring it up on the site meta in order to see if the community is interested in the idea. Don't expect too much from SE at this point, but if you have a solid plan you can always contact them using the Contact Us page to see if they have anything for yo to keep in mind.
