  We report on the precise mass measurements of the $^{91}$Sr and $^{95}$Y
isotopes performed using the JYFLTRAP double Penning trap mass spectrometer.
The mass-excess values from this work, ${\mathrm{ME}(^{91}\mathrm{Sr}) =
-83645.5(13)}$ keV and ${\mathrm{ME}(^{95}\mathrm{Y}) = -81226.4(10)}$ keV,
deviate by 6.5(52) keV and $-18(7)$ keV from the Atomic Mass Evaluation 2020
(AME20). In the case of $^{91}$Sr the new result disagrees with the ISOLTRAP
value, while for $^{95}$Y, it agrees with the older JYFLTRAP value.
