An observation deck is a platform equipped with a railing situated upon a tall architectural structure or on a mountain. To avoid accidents or suicides, the railing is often extra high or supplemented with a wire fence. An observation deck can also be situated in a room, equipped with windows. For photographing, open observation decks are better, as on glasses often reflections occur, especially with flash photography. However high railings with too low grid width are also bad for photographing as the grid occurs in the picture. Nevertheless closed observation decks have the advantage of protecting viewers from windy or stormy weather. Many observation decks are equipped with coin operated telescopes, which often offer a superior view of faraway objects.

This list contains the highest-elevated observation decks and includes carriageways of bridges and tops of dams, if these are accessible for the public and in case of bridges the maximum height of the carriageway is determined by the height of the bridge pillars. It does not contain aerial tramways as the heights of these are often determined by topography ( the tallest aerial tramway support pillar, belonging to Glacial Aerial Tramway Kaprun III at Kitzbühel, Austria, is with 113.6 metres height much less tall than the height of the observation decks of many TV towers).
