Blackford has been an MP since 2015 and led the SNP's Westminster group for five years.
He stepped down as group leader in December to avoid a possible challenge from his eventual successor, Stephen Flynn.
Blackford was a close ally of Nicola Sturgeon and played a significant role in making the SNP a prominent force in Scottish and UK politics.
He is currently working on a paper on Scotland's industrial future and will continue as the first minister's business ambassador.
