The former SNP MP, who was the MP for Ochil and South Perthshire between 2015 and 2017, is one of the latest candidates to join the party and will stand in the Central Scotland region.
Ms Ahmed-Sheikh, who was the SNP’s women’s and equalities convener until 2018, previously worked with Mr Salmond on his television show for the Russia Today channel.
On Wednesday, Alba said it had met its target of standing four candidates in each regional list in Scotland – a total of 32. It will not be fielding candidates in the constituency ballots.
Alba is due to hold a national candidate launch event on Thursday.
Revealing the list of 32 candidates, the former First Minister and Alba Party leader Alex Salmond said: “This is a thrilling list with a depth of talent, diversity and experience which I am proud t lead into the election.
"Five days ago I asked how many would rally to the Alba standard. The answer comes in this hugely impressive list today.
"Alba is set to make a big impact as we seek to build the #Supermajority for independence in the next Scottish Parliament.”
