description The large acceptance and high momentum resolution as well as the significant particle identification capabilities of the NA49 experiment at the CERN SPS allow for a broad study of fluctuations and correlations in hadronic interactions. In the first part recent results on event-by-event charge and $\left \langle{p_{t}}\right \rangle$ fluctuations are presented. Charge fluctuations in central Pb+Pb reactions are investigated at three different beam energies (40, 80, and 158 AGeV), while for the $\left \langle{p_{t}}\right \rangle$ fluctuations the focus is put on the system size dependence at 158 AGeV. In the second part recent results on Bose Einstein correlations of $h^{-}h^{-}$ pairs in minimum bias Pb+Pb reactions at 40 and 158 AGeV, as well as of $K^{+}K^{+}$ and $K^{-}K^{-}$ pairs in central Pb+Pb collisions at 158 AGeV are shown. Additionally, other types of two particle correlations, namely $\pi p$, $\Lambda p$, and $\Lambda \Lambda$ correlations, have been measured by the NA49 experiment. Finally, results on the energy and system size dependence of deuteron coalescence are discussed.
