We present the latest semileptonic $B$ decay measurements from the Belle II experiment, which aims to determine the magnitudes of the CKM matrix elements $|V_{cb}|$ and $|V_{ub}|$. The data sample used for the results presented was collected at the $\Upsilon(4S)$ resonance and corresponds to an integrated luminosity of 189 fb$^{-1}$.
$|V_{cb}|$ is determined from analyzing $B \rightarrow D^* \ell \nu$ and $B \rightarrow D \ell \nu$ decays. $|V_{ub}|$ is measured via $B \rightarrow \pi \ell \nu$ decays.
