1169 Alwine, provisional designation 1930 QH, is an asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 30 August 1930, by German and Italian astronomers Max Wolf and Mario Ferrero at Heidelberg Observatory in southwest Germany.

Alwine orbits the Sun at a distance of 2.0–2.7 AU once every 3 years and 6 months (1,290 days). Its orbit has an eccentricity of 0.15 and an inclination of 4° with respect to the ecliptic. As no precoveries were taken, and no prior identifications were made, Alwine's observation arc begins with its official discovery observation at Heidelberg in 1930.

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Alwine measures 7.89 kilometers in diameter, and its surface has an albedo of 0.179. Based on a generic magnitude-to-diameter conversion, its diameter is between 7 and 17 kilometers for an absolute magnitude of 12.8 and an albedo in the range of 0.05 to 0.25. As of 2017, no rotational lightcurves have been obtained. The body's rotation period, pole and shape remain unknown.

This minor planet is named after a common German female name. Any reference of this name to a person or occurrence is unknown.
