contents The aim of this paper is to describe the topological $K$-ring, in terms of generators and relations, of a Springer variety $\mathcal{F}_λ$ of type $A$ associated to a nilpotent operator having Jordan canonical form whose block sizes form a weakly decreasing sequence $λ=(λ_1,\ldots, λ_l)$. Our description parallels the description of the integral cohomology ring of $\mathcal{F}_λ$ due to Tanisaki and also the equivariant analogue due to Abe and Horiguchi.
