A lectern is a reading desk with a slanted top, on which documents or books are placed as support for reading aloud, as in a scripture reading, lecture, or sermon. A lectern is usually attached to a stand or affixed to some other form of support. To facilitate eye contact and improve posture when facing an audience, lecterns may have adjustable height and slant. People reading from a lectern, called lectors, generally do so while standing.

In pre-modern usage, the word lectern was used to refer specifically to the "reading desk or stand ... from which the Scripture lessons (lectiones) ... are chanted or read." One 1905 dictionary states that "the term is properly applied only to the class mentioned [church book stands] as independent of the pulpit." By the 1920s, however, the term was being used in a broader sense; for example, in reference to a memorial service in Carnegie Hall, it was stated that "the lectern from which the speakers talked was enveloped in black."
