Adrian Christopher Roos is a South African politician and a Member of Parliament in the National Assembly for the Democratic Alliance party. Within the DA's Shadow cabinet, he served as Deputy Shadow Minister of Home Affairs from 2020 until 2024.

Background Roos holds LLB and BSc degrees and is an admitted advocate of the North Gauteng High Court. He is a former national chairperson of the Geoinformatics Society of South Africa.

On 27 June 2019, he became an alternate member of the Portfolio Committee on Home Affairs. He became a full member of the committee on 7 February 2020 and was appointed Shadow Deputy Minister of Home Affairs.

Roos criticised the electoral amendment bill that would allow for individuals to stand for election to parliament and provincial legislatures as independent candidates after it was passed by the National Assembly in October 2022, arguing that the bill discriminates against independent candidates because it consigns them to contesting only the regional lists by treating provinces as constituencies, but bars them from standing as candidates on the national proportional representation list.

Having been re-elected to the National Assembly in the 2024 general election, Roos was elected to serve on the Magistrates Commission.
