Juan 11:2

And it was that Mary who anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.

We are not primarily concerned here with the distinction between various Mary's mentioned in the New Testament. Identification of this Mary with the gross sinner who bathed the Lord's feet with her tears in the house of Simon the Pharisee is rejected. There were at least two anointings of Jesus, possibly three; and the Roman Catholic interpretation of melding all three into one is without doubt incorrect. John here identified this Mary with the one in Mark 14:3-9, the event recorded there taking place in the home of Simon the leper; and there is no basis for supposing that he was the same as Simon the Pharisee.
