Sir Ralph Josselyn (or Jocelyn) KB (died 25 October 1478) was a 15th-century English politician who held several political offices, including two terms as Lord Mayor of London.
[2] As Josselyn's elder brother inherited their father's lands on his death, he went to make his career in London.
[1] During this term, he was one of four London citizens made a Knight of the Bath, at the coronation of Edward IV's queen, Elizabeth Woodville.
[5] In 1471, he raised a force to repel the assault of Thomas Neville, Bastard of Fauconbridge, when the latter attacked the city in an unsuccessful attempt to rescue the imprisoned King Henry VI from the Tower of London.
He procured massive quantities of bricks and lime, levied taxes to pay for the significant costs of the repairs, and provided for the work to be supervised by a hand-picked panel of citizens representing each of the city's wards.
