  In this paper, we show that wreath products of groups have linear divergence,
and we generalise the argument to permutational wreath products. We also prove
that Houghton groups $\mathcal{H}_m$ with $m\geq 2$ and Baumslag-Solitar groups
have linear divergence. Finally, we show that wreath products of graphs and
Diestel-Leader graphs have linear divergence.
