A Bachelor's Wife is a 1919 silent drama film directed by Emmett J. Flynn and starring Mary Miles Minter.

[1] In the weeks before its release, some film magazines listed the feature under its working title “Mary O’Rourke.” [2] As described in Motion Picture Herald,[3] Mary O’Rourke (Minter) arrives in America from Ireland and finds her young friend and baby deserted by the husband.

Mrs. Stuyvesant, an invalid, is delighted with the child, and mistaking Mary for her daughter-in-law, invites her to stay and take charge of the house.

The doctor informs Mary that she must comply with the old lady's request, as a shock might prove fatal to her.

Mary confronts him with the marriage license, which it appears belongs to J. Frederick Stuyvesant, a cousin.
