The Objective Bayes meetings are one of the longest running and preeminent series of meetings in Bayesian statistics; this will be the tenth meeting. In addition to 21 invited talks and discussions, there will be a day of tutorials and a poster session. The meeting will be held in conjunction with the EFab@ Bayes250 meeting and Bayes 250 Day, a special event to commemorate the 250th anniversary of the publication of Bayes paper. There will be some support for students and new researchers to attend the meeting; apply at the meeting website.
