Brenda Cecilia Agüero (born 2 June 1995) is an Argentine serial killer and former neonatal nurse convicted of the murder of five babies under her care.

Between March and June 2022, Agüero deliberately injected healthy babies with overdoses of potassium or insulin (or both), killing five and causing decompensations in eight others.

Agüero was charged with five counts of "aggravated murder for applying the insidious method of potassium incompatible with life". Agüero was later charged with eight other counts of attempted murder.

The trial against Agüero and 10 provincial officials began on 6 January 2025.

On 18 June 2025, Agüero was found guilty of all charges and sentenced to life in prison.
