We have obtained V, I, and K band photometry for 290 square arcminutes in the Praesepe open cluster. The photometry reliably reaches 0.08 M⊙. We find six probable cluster members in the range 0.40 M> M > 0.08 M. The mass function we derive for Praesepe is similar to the field star IMF. We conclude that dynamical processes that can lead to evaporation of low-mass members from stellar clusters have not occurred to a substantial extent in Praesepe.
