(11436) 1969 QR, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 3.7 kilometers in diameter. It was discovered on 22 August 1969, by Czech astronomer Luboš Kohoutek at Bergedorf Observatory in Hamburg, Germany.

The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,212 days). Its orbit has an eccentricity of 0.14 and an inclination of 7° with respect to the ecliptic. As no precoveries were taken, the asteroid's observation arc starts with its discovery observation in 1969.

A rotational light-curve for this asteroid was published by several Hungarian astronomers in August 2005. The photometric observations gave a rotation period of 7000265000000000000♠2.65 hours with a brightness variation of 0.27 magnitude (U=2).

The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its orbital family – and calculates a diameter of 3.7 kilometers.
