Herbert Onyewumbu Wigwe is a Nigerian banker and entrepreneur. He is currently CEO and Group managing director of Access Bank plc, one of Nigeria's top five banking institutions, after succeeding his business partner, Aigboje Aig-Imoukhuede in January 2014.

Mr. Wigwe started his professional career with Coopers and Lybrand Associates, an international firm of Chartered Accountants.

He spent over 10 years at Guaranty Trust Bank where he managed several portfolios including Financial institutions, Corporates and Multinationals. He left Guaranty Trust as an Executive Director to co-lead the transformation of Access Bank Plc in March 2002 as Deputy Managing Director.

Access Bank is now one of the top five banks in Nigeria and ranked among the top 500 global banks according to a 2015 report by The Banker magazine and is aiming to be Africa's top bank. It currently serves over 6.5 million account-holders, through 350 branches and with more than 1,500 ATMs in major centres across Nigeria, Sub-Saharan Africa and the UK. Herbert Wigwe is estimated to be worth N32.1 billion.
