Midweek was a British weekly radio magazine series broadcast on BBC Radio 4. It was aired on Wednesday at 09.00 and repeated later the same day at 21.00. For most of its run it was presented by Libby Purves and each week several guests discussed various topics with her. Start the Week and Stop the Week, also broadcast on Radio 4, employed similar formats. The programme ended in March 2017 as part of a schedule change.
