Ummy Ally Mwalimu (born 5 September 1973) is a Tanzanian politician belonging to the ruling Chama Cha Mapinduzi (CCM) party.

She is currently a Member of Parliament for Tanga Constituency and most recently served as the Minister of Health until August 2024, when she was succeeded by Jenista Mhagama.

[2] In 2015, the newly elected President John Magufuli appointed Mwalimu as Minister for Health, Community Development, Gender, Elderly and Children.

This stance has been condemned by NGOs and goes against UNAIDS recommendation that providing water-based lubricants along with condoms can help curb the spread of HIV.

[4] Mwalimu has stated her support for ending underage marriage and assured activists she would table a bill in Parliament amending the laws that allow persons under the age of 18 to get married.
