William Dening Glyde (c. 1826 – 4 January 1901) was a wheat merchant and politician in the colony of South Australia. Glyde was born the son of Elijah Glyde, a gentleman farmer of Waylord, Somerset and his wife Sarah, née Dening or Denning. After working on his father's property for about 15 years he decided in 1866 to try his luck in South Australia, his brother S. D. Clyde having emigrated to New Zealand some five years earlier. Glyde and his wife arrived in South Australia in January 1867.
