Lean is focused on the elimination of waste. Six Sigma is the application of statistical analysis to manage the mean values and variances of outcomes.

Lean may utilize 6σ as a method, and 6σ often uses elements of lean during parts of the project.

I'd slightly correct Keith's comment - Lean is focused on improving the flow of value to stakeholders and part of that is about reducing waste.

LSS provides a richer set of tools for an Operational Excellence practitioner than just Six Sigma. For example, the concept of value streams and value stream mapping is valuable as a starting point for both reducing waste but also reducing variation.
