Sister Kenny is a 1946 American biographical film about Sister Elizabeth Kenny, an Australian bush nurse, who fought to help people who suffered from polio, despite opposition from the medical establishment. The film stars Rosalind Russell, Alexander Knox, and Philip Merivale.

The film was adapted by Alexander Knox, Mary McCarthy, Milton Gunzburg (uncredited), and Dudley Nichols from the book And They Shall Walk, by Elizabeth Kenny and Martha Ostenso, and directed by Dudley Nichols.

The "Sister" in the title does not refer to being a religious sister, but rather a rank she had held as a nurse in the Australian Army. It is also a term for a senior RN (which Kenny was not).
