The 34-year-old's income of $56m (£45.7m) lands her below seventh-placed male actor Adam Sandler.
She earned $15.5m (£12.6m) more than she did in 2018, thanks largely to the success of Avengers: Endgame.
Modern family actor Sofia Vergara is the only other woman to break into the overall top 10.
Earlier this week, Dwayne Johnson was announced as the highest-paid actor of the last 12 months, making $89.4m (£73.6m) according to the latest annual rankings from the financial experts.
