11755 Paczynski (2691 P-L) is a Nysian asteroid from the main belt, discovered on September 24, 1960, by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.

It is named after Bohdan Paczyński (1940–2007), a Polish-born astrophysicist known for his theoretical work on gamma ray bursters — he was an early proponent of their being at cosmological distances — and for leading searches for gravitational lensing by low-mass stars and substellar objects.[2]
