The Skrwa Lewa (Left Skrwa; in Polish also Skrwa Lewobrzeżna or Skrwa Południowa) is a river of Poland, and a left tributary of the Vistula.

It flows through the Gostynin-Włocławek Landscape Park.

From the town of Gostynin to its mouth, the Skrwa Lewa is a kayaking area.

Its counterpart, the Skrwa Prawa (Right Skrwa), joins the Vistula about three miles downstream on the opposite bank.
