Ayot St Lawrence is a small village in Hertfordshire, between Harpenden and Welwyn.

George Bernard Shaw lived in the village, at Shaw's Corner, from 1906 until his death in 1950. The house is open to the public as a National Trust property.

The village has one pub, the Brocket Arms, which is reputed to be haunted.

The village has two churches. The old one, in the centre of the village, was partially demolished in 1775, because it was obstructing the view from Sir Lionel Lyde 's new home.

The new St Lawrence church was designed in a neo-classical style by Nicholas Revett and features a Palladian-style frontage with Doric columns.
