The longest English word, at 45 letters, is ‘pneumonoultramicroscopicsilicovolcanoconiosis’.

False - that title belongs to the Chemical name of titin, the largest known protein, at 189,819 characters:

Methionylthreonylthreonylglutaminylarginyl[…]isoleucine (full name)

Second place goes to a 183 character word transliterated from Ancient Greek:

Lopadotemachoselachogaleokranioleipsanodrimhy-
potrimmatosilphioparaomelitokatakechymenokich-
lepikossyphophattoperisteralektryonoptekephall-
iokigklopeleiolagoiosiraiobaphetraganopterygon

Pneumonoultramicroscopicsilicovolcanoconiosis sits firmly in third place, there are disputes as to its legitimacy, as it is claimed that this word was invented purely to serve as a long word. It should be noted that, Pneumonoultramicroscopicsilicovolcanoconiosis is the longest english word to be in a current major dictionary.
