The principal speaker or presentation at a conference or event, setting the overarching theme or message.
A keynote presentation is typically the most prominent, highest-profile session in a conference programme. Keynote speakers are often industry leaders, authors, or public figures chosen for their authority and ability to inspire the audience. Keynotes are usually placed at the start of a conference to set the tone, or at the end to create a memorable closing. They typically run 30–60 minutes and are held in the plenary room.
