Let ɸ be an analytic map on the open unit disk D in the complex plane such that ɸ (D)⊂ D. The composition operator DCɸ : is defined by

DCɸ (f)=(foɸ)

In this paper, the boundedness and compactness of the composition op­erator DCɸ from the weighted Bergman Nevanlinna spaces to Zygmund spaces are  investigated.
