Gilbert Blythe is a character in Canadian author Lucy Maud Montgomery's Anne of Green Gables series of novels.

Throughout the series, Gilbert is depicted as a fair, practical and reliable man, who is inclined to have a "common sense" view of things.

He eventually becomes a highly respected doctor in the fictional town of Glen St Mary, Prince Edward Island, where he lives with his wife Anne, their children and the family's spinster housekeeper, Susan.

In response, Anne smashes her slate over his head in anger, and despite his attempts to apologize, she refuses to forgive him for several years.

When Anne refuses his offer of friendship after the incident, Gilbert decides to respond in kind and stops openly trying to gain her attention.

Following his time at Queens, Gilbert decides to teach at the Avonlea school to finance his future college education.

Gilbert teaches at the White Sands School and Anne, after learning of his noble act, finally forgives him.

Gilbert seems to concede defeat and Anne believes that he has become involved with another student, Christine Stuart, who is later revealed to be only a friend.

Anne, who has recently refused a proposal of marriage from Roy Gardner after realizing that she does not love him, is shocked to learn that Gilbert may die.

The two marry in Anne's House of Dreams and move to the town of Glen St. Mary, where Gilbert takes over his uncle's medical practice.

Still living in Glen St. Mary, Gilbert and Anne are the grandparents of at least five children, several of whom are off to fight in World War II.
