Catherine 'Kate' Thomson Dickens was the wife of English novelist Charles Dickens, with whom he fathered 10 children.

Catherine was the daughter of George Hogarth, editor of the Evening Chronicle where Dickens was a young journalist. They were married on April 2, 1836 in St. Luke's Church, Chelsea and honeymooned in Chalk, near Chatham. Dickens found Catherine an increasingly incompetent mother and housekeeper and seemed to blame her for the birth of their 10 children. Their separation, in 1858, was much publicized and rumors of Dickens unfaithfulness abounded, which he vehemently denied in public. Dickens and Catherine had little correspondence after the break, Catherine moving to a house in London with oldest son, Charley, and Dickens retreating to Gad's Hill in Kent with Catherine's sister, Georgina, and all of the children except Charlie remaining with him. On her deathbed in 1879 she gave her collection of Dickens' letters to daughter Kate instructing her to "Give these to the British Museum, that the world may know he loved me once."
