Peskin, 25, becomes the latest Banyana star to make a move abroad within an exciting new era for the South African women's national team.
Having spent four years in the United States before returning to South Africa in 2018, it's another major step in the career for the talented Cape-Town born attacker.
"I come here with the ambition to help the club by scoring goals," Peskin told the club's website. "It is my role. The Girls have had a difficult start to the season, but we need to keep going.
"It is not my first experience far from South Africa since I studied in the United States, but this is may first time playing in Europe now here with Toulouse.
"The level is higher here it seems to me, more physical, with more long balls and duels I hope to make my speed speak and be decisive quickly."
