London/2026 events
Welcome to the list of OpenStreetMap related events in London for 2026
These events are free and open to all. We normally have a mixture of old OpenStreetMap hands and new people coming along to find out more. The events might include mapping, or might include "Q&A" presentations, but mostly we're just sitting around in a pub having a friendly chat about little things like mapping the world and releasing it for free! We hope you'll join us! Everyone and anyone is welcome.
Upcoming Events
Wed 16th Sept - Geomob
On the evening of Wednesday September 16th there's a #geomob event at geovation in Clerkenwell. Presentations on a variety of map/geo topics, sometimes including OpenStreetMap. They'll be OSMers in the audience, and in the pub afterwards, trying to blend in with rest of the geo-industry! This time there'll be a talk from long time OSMLondoner User:Matt!

Wed 23rd Sept - The Blue Posts, Newman St
On Wednesday 23rd September we'll have a pub meet-up at The Blue Posts pub, Newman St, from 7:00pm. Whether you're a mapper, map user, or just curious, come join us for map chat and beers!
Warning! There are several Blue Posts pubs. Make sure you go to the right one! We're going to the one on Newman Street. It is here on the map, just north of Oxford St. Nearest tube is Tottenham Court Road. Warning 2! This pub has an upstairs which is quite well hidden, but we may well be up there. If you think you may have trouble recognising anyone, turn up at 7:30pm when the group will be more assembled, and look out for maps or OpenStreetMap hi-viz vests. Also take Harry's number: O7979815O13
The pub serves food and so some/most of us will probably be eating there
Mark yourself as "attending" on osmcal.org if you fancy it. Not everyone bothers signing up. We normally expect between 5 & 15 people at the pub.
Missing Maps London (assorted ongoing)
Missing Maps London is still running regular humanitarian mapping events, although mostly online only these days. They have monthly larger "training" events welcoming people who are new to OSM editing, or new to humanitarian mapping tasks, and they also have some smaller events for experienced mappers.
See London mentions on the events page at https://missingmaps.org/events/
Future events
We'll use this wiki page to announce events, as well as _new_hue.svg){kind=small}

@OSMLondon
Announcements may come at short notice!
There’s lots of other events in London e.g. tech meet-up groups, for which OpenStreetMap is relevant. Please use the wiki to pro-actively coordinate the setting up of an “OpenStreetMap presence” at these events… or just go along (Other OSMers may or may not be there)
We’ve got a rather out-of-date list of London event venues for future events of a non-pub format. Please rewrite that page if you have ideas or if your organisation would like to host or sponsor an event!
