  We define a manifestly supersymmetric version of the $T \overline{T}$
deformation appropriate for a class of $(0+1)$-dimensional theories with
$\mathcal{N} = 1$ or $\mathcal{N} = 2$ supersymmetry, including one
presentation of the super-Schwarzian theory which is dual to JT supergravity.
These deformations are written in terms of Noether currents associated with
translations in superspace, so we refer to them collectively as
$f(\mathcal{Q})$ deformations. We provide evidence that the $f(\mathcal{Q})$
deformations of $\mathcal{N} = 1$ and $\mathcal{N} = 2$ theories are on-shell
equivalent to the dimensionally reduced supercurrent-squared deformations of
$2d$ theories with $\mathcal{N} = (0,1)$ and $\mathcal{N} = (1,1)$
supersymmetry, respectively. In the $\mathcal{N} = 1$ case, we present two
forms of the $f(\mathcal{Q})$ deformation which drive the same flow, and
clarify their equivalence by studying the analogous equivalent deformations in
the non-supersymmetric setting.
