10 Gardai and Sergeants got over €46,000 each in overtime last year.
According to freedom of information figures, the Gardai's total overtime bill for 2021 was nearly €15m more than the previous year.
Last year's bill was almost €114m - compared to less than €99m the previous year.
Two Gardaí and three Sergeants got over €50,000 each in overtime last year too.
Sinn Féin's justice spokesman, Martin Kenny, says the figures are excessive.
"Nobody should be doubling, or more than doubling their salary with overtime."
"I think all aspects of it need to be reviewed."
"I think it also reflects that we need to have more Gardaí trained, and I know the Government has a commitment to train more Gardaí this year, but we need that every year."
