The South African Police Star for Distinguished Leadership was a high-ranking decoration, that existed between 1979 and 1986.

Recipients were entitled to use the post-nominal letters SED, standing for Stella Excellentis Ductus, the Latin form of the name.

Instituted on 1 May 1979, the SED was awarded to general officers of the South African Police for distinguished leadership, meritorious service contributing to state security, and outstanding service to heads of state or government.

In the centre is depicted a stylised aloe plant on a blue-bordered white disc on a gold diamond-shaped plaque.

After that date, police generals were awarded the Order of the Star of South Africa (Non-Military) instead.
