Lucy Muringo Gichuhi (/ɡɪˈtʃuːi/; née Munyiri; born 23 September 1962) is an Australian politician who served as a Senator for South Australia from 2017 to 2019.

[4] Gichuhi originally sat in the Senate as an independent, after refusing to join the Family First Party in merging into the Australian Conservatives.

She worked at Ernst and Young and the South Australian Auditor-General's department developing programs for migrants and international students.

Day resigned on 1 November 2016 after the collapse of his homebuilding business, and was retroactively disqualified on 5 April 2017 for having an indirect interest in a building where the Commonwealth was paying rent for his Commonwealth-funded electorate office.

At the High Court's direction, the Australian Electoral Commission performed a special recount of Senate votes in South Australia.

[15] Senator Gichuhi was born in Kenya and is the first person of Black African descent to be elected to the Australian Parliament.

[14] On 2 February 2018, Gichuhi joined the Liberals, with Prime Minister Malcolm Turnbull personally welcoming her to the party in a video posted to his Twitter account.

[24] In July 2018, Gichuhi was demoted to an unwinnable fourth position on the Liberal Party's South Australian Senate ticket for the next federal election.

[25][26][27] In September, Gichuhi revealed that she was asked during her preselection process if she thought Turnbull was the right person to lead the Liberal Party.

[29] Despite having grown up in rural Kenya, Gichuhi says that the concept of poverty never entered her mind, and she is firmly against government handouts as she believes "they create victims and nobody wins".
