Aircraft nacelles having adjustable chines are described. An example apparatus includes a first chine rotatably coupled to a nacelle at a first location about an outer circumference of the nacelle. The first chine is rotatable relative to the nacelle about an axis of rotation. The example apparatus further includes a second chine fixedly coupled to the nacelle at a second location about the outer circumference of the nacelle. The second location is circumferentially offset from the first location.
