Londynn is a creative respelling of the place name London, which derives from the Roman name Londinium, of uncertain origin. The city name has been used as a given name since the late 20th century, particularly for girls. This respelling with a double 'n' and final 'y' emerged in the 2000s as part of a trend of unique spellings and geographical names.
