So Dear to My Heart is a 1948 American live-action/animated comedy-drama film produced by Walt Disney and released by RKO Radio Pictures. Its world premiere was in Chicago, Illinois, on November 29, 1948. Like 1946's Song of the South, the film combines animation and live action. It is based on the 1943 Sterling North book Midnight and Jeremiah. The book was revised by North to parallel the film's storyline amendments and then re-issued under the same title as the film.

The film was a personal favorite of Walt Disney, since it re-created on film one of the most memorable times of his life, growing up on a small farm in the American Midwest at the turn of the twentieth century. Walt said: "So Dear was especially close to me. Why, that's the life my brother and I grew up with as kids out in Missouri". Walt had intended that this would be the first all live-action Disney feature film, but his distributor, RKO, convinced him that when audiences saw the word "Disney", they expected animation. Thus they split the difference.

So Dear to My Heart was the final film appearance of Harry Carey.
