As Palestras de Hibbert são uma série anual de palestras não sectárias sobre questões teológicas. Eles são patrocinadas pela Hibbert Trust, que foi fundada em 1847 pelo Unitarista Robert Hibbert com o objetivo de defender "o exercício irrestrito do julgamento privado em questões religiosas". Nos últimos anos, as palestras foram transmitidas pela BBC .
