Olufunmilayo Adunni Olayinka (née Famuagun; 20 June 1960 – 6 April 2013), was a Nigerian banker and politician who served as the deputy governor of Ekiti State from 2010 until her death in 2013.

Until her election as the deputy governor of Ekiti State, she was head of corporate services, Ecobank Transatlantic Inc., where she was responsible for communicating the bank's activities to the public, relationship management with the public and providing feedback to management as it relates to the total image of the bank.

On 14 October 2010, after a 3+1⁄2-year prolonged re-election process and court battle, an Elections Appeal Tribunal sitting in Ilorin, Kwara State, Nigeria sacked former governor Segun Oni of the Peoples Democratic Party (PDP) and declared Dr Kayode Fayemi of the Action Congress of Nigeria (ACN) as the new governor of Ekiti State.

[10] Mrs Olufunmilayo Olayinka was subsequently sworn in as the substantive deputy governor of Ekiti State by virtue of her existing role as the running mate of Dr Kayode Fayemi during the 2007 governorship elections.

Olayinka died in the evening of 6 April 2013 after a long battle with cancer[2] and she was laid to rest in Ado-Ekiti.
