In Our Time is a live BBC radio discussion series and podcast exploring a wide variety of historical topics, presented by Melvyn Bragg, since 15 October 1998. It is one of BBC Radio 4's most successful discussion programmes, acknowledged to have "transformed the landscape for serious ideas at peak listening time". As of 21 June 2018, 808 episodes have been aired and the series attracts a weekly audience exceeding two million listeners.

The series, devised and produced by Olivia Seligman (with others) and currently produced by Simon Tillotson with Victoria Brignell, runs weekly throughout the year on BBC Radio 4, except for a summer break of approximately eight to ten weeks between July and September. Each programme covers a specific historical, philosophical, religious, cultural or scientific topic. In a November 2009 interview, Bragg described how he prepares for each show: "It's not easy, but I like reading. I enjoy what was called swotting in my day. I get the notes late Friday afternoon for the following Thursday morning. I find all the spare time I can for reading, get up very early on a Thursday morning, have a final two hours of nervousness, and away we go."
