Excited states in $^{209}\mathrm{Fr}$ have been studied using the $^{197}\mathrm{Au}(^{16}\mathrm{O},4n)^{209}\mathrm{Fr}$ reaction with pulsed beams and $\ensuremath{\gamma}$-ray and electron spectroscopy. A comprehensive scheme has been established up to an excitation energy of about 6 MeV and spins of about $49/2\ensuremath{\hbar}$. Several isomers have been identified including a ${J}^{\ensuremath{\pi}}=25/{2}^{+}$, $\ensuremath{\tau}=48(3)$ ns state at 2130 keV and a $606(26)$ ns, $45/{2}^{\ensuremath{-}}$ state at 4660 keV. The latter state decays via an enhanced $E3$ transition with a strength of 28.8(12) W.u. It can be identified with a similar isomer in the heavier odd isotopes $^{211}\mathrm{Fr}$ and $^{213}\mathrm{Fr}$, arising from the maximal coupling of the five valence protons in the $\ensuremath{\pi}{h}_{9/2}^{3}{i}_{13/2}^{2}$ configuration. The systematics of the yrast states in the odd-$A$ isotopes are discussed, including the presence of states arising from the main proton configurations coupled to the ${p}_{1/2}$, ${f}_{5/2}$, and ${i}_{13/2}$ neutron holes. Shell-model configurations are assigned to many of the observed states. The isotopic assignment differs from earlier work, which is shown to be erroneous.
