We study the distribution of squares in a Piatetski-Shapiro sequence $(\lfloor n^c\rfloor)_{n\in\mathbb N}$ with $c \gt 1$ and $c\not\in\mathbb N$. We also study more general equations $\lfloor n^c\rfloor = sm^2$, $n,m\in \mathbb N$, $1\le n \le N$, for an integer $s$ and obtain several bounds on the number of solutions for a fixed $s$ and on average over $s$ in an interval. These results are based on various techniques chosen depending on the range of the parameters.
