1101 Clematis is a dark Alauda asteroid from the outer region of the asteroid belt that was discovered by German astronomer Karl Wilhelm Reinmuth on September 22, 1928, in Heidelberg.[2] Initially it received the designation 1928 SJ, it was named for the clematis flower.

Photometric observations made in 2003 at the Santana Observatory in Rancho Cucamonga, California, give a synodic rotation period of 12.68 ± 0.01 hours. The light curve shows a brightness variation of 0.40 ± 0.05 in magnitude.[3]

Clematis is a member of the Alauda family (902),[1] a large family of typically bright carbonaceous asteroids and named after its parent body, 702 Alauda.[4]:23

According to a different study, this object is also the namesake of the Clematis family, a small family of 5–16 asteroids hence they may have arisen from the same collisional event. All members have a relatively high orbital inclination.[5]
