Georgieva, who was in the debt-ridden southern African nation this week, said a deal was in everyone's interest as otherwise Zambia was not in a position to start paying what it owed.
"I am confident that the creditors will reach agreement," the International Monetary Fund head told a press conference in Lusaka.
"It is clear from my visit that Zambia is doing its part, so I strongly encourage creditors to move forward."
As the Covid-19 pandemic battered Africa in 2020, Zambia became the first country on the continent to default on its foreign debt -- estimated at $17.3 billion.
It has sought help through a G20 mechanism, but implementation has been slow, with the United States accusing China -- the main creditor to many African nations -- of dragging its feet.
US Treasury Secretary Janet Yellen, who was also visiting the country this week, said on Monday restructuring Zambia's debt was a "top priority".
Since the 2021 election of businessman-turned politician President Hakainde Hichilema, the country has made progress in restoring relations with donors.
Last year, the IMF approved a $1.3 billion loan to help Zambia restore fiscal stability.
Georgieva said the IMF was impressed with the improvements Zambia was making in the use of public resources, saying as a result of prudent expenditure, the copper-rich nation was "redirecting" its funds "to much-needed spending on education and health".
"Zambia is making tremendous progress on reforms, at what is a particularly challenging time for the world economy" Georgieva said.
