1296 Andrée, provisional designation 1933 WE, is a stony Nysian asteroid from the inner regions of the asteroid belt, approximately 25 kilometers in diameter. It was discovered on 25 November 1933, by French astronomer Louis Boyer at the North African Algiers Observatory, Algeria, and named after the discoverer's niece.
Andrée is a member of the Nysa family, named after its namesake 44 Nysa and one of the smaller asteroid families in the main-belt. It orbits the Sun at a distance of 2.1–2.8 AU once every 3 years and 9 months (1,373 days). Its orbit has an eccentricity of 0.14 and an inclination of 4° with respect to the ecliptic. It was first identified as 1925 TA at Heidelberg Observatory in 1925, extending the body's observation arc by 8 years prior to its official discovery observation.
In January 2002, a rotational lightcurve of Andrée was obtained from photometric observations by French amateur astronomer Laurent Bernasconi. Lightcurve analysis gave a well-defined rotation period of 5.178 hours with a brightness variation of 0.27 magnitude (U=3). In October 2004, a concurring lightcurve with a period of 5.18366 hours and an amplitude of 0.23 was obtained by French astronomers Cyril Cavadore and Pierre Antonini (U=3).
