The distance Laplacian matrix of a connected graph G is defined as , where is the diagonal matrix of the vertex transmissions in G and is the distance matrix of G. The largest eigenvalue of is called the distance Laplacian spectral radius of G. In this paper, we determine the graphs with the maximum distance Laplacian spectral radius and the minimum distance Laplacian spectral radius among all the bicyclic graphs with given order, respectively.
