Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. Atenolol, however, does not seem to improve mortality in those with high blood pressure. Other uses include the prevention of migraines and treatment of certain irregular heart beats. It is taken by mouth or by injection into a vein. It can also be used with other blood pressure medications.

Common side effects include feeling tired, heart failure, dizziness, depression, and shortness of breath. Other serious side effects include bronchospasm. Use is not recommended during pregnancy and other medications are preferred when breastfeeding. It works by blocking β1-adrenergic receptors in the heart, thus decreasing the heart rate and workload.

Atenolol was patented in 1969 and approved for medical use in 1975. It is on the World Health Organization's List of Essential Medicines as an alternative to bisoprolol. It is available as a generic medication. The defined daily dose is 75 mg by mouth. In the United States, at this dose, the wholesale cost per month is more than US$25 as of 2021. In the United Kingdom, a month of treatment costs the NHS less than £1.50 as of 2020. In 2018, it was the 42nd most commonly prescribed medication in the United States, with nearly 19 million prescriptions.
