According to the information from  naitsirhc  I wanted to find the official API documentation  Here are my finding and some sample code   I created a matplotlib Axes object by seaborn scatterplot    The ax get legend   will return a matplotlib legned Legend instance  Finally  you call  remove   function to remove the legend from your plot   ax   sns scatterplot          lg   ax get legend    lg remove    If you check the matplotlib legned Legend API document  you won t see the  remove   function  The reason is that the matplotlib legned Legend inherited the matplotlib artist Artist  Therefore  when you call ax get legend   remove   that basically call matplotlib artist Artist remove    In the end  you could even simplify the code into two lines  ax   sns scatterplot         ax get legend   remove
