The festival, which opens on 11 February, will show Nicolas Roeg's 1976 sci-fi film The Man Who Fell to Earth.
It starred Bowie in his first movie role as an alien on a quest for water to save his dying planet.
Also screening will be Ang Lee's 1995 period drama Sense and Sensibility, in which Rickman played Colonel Brandon.
The film won the Berlinale's highest prize, the Golden Bear, in 1996.
Both Bowie and Rickman died in January from cancer. They were both aged 69.
Announcing the special screenings, Berlinale director Dieter Kosslick said: "David Bowie was a tremendous musician, an avant-garde artist who expressed his creativity in many disciplines."
Bowie lived in Berlin in the late 1970s where he recorded his experimental art rock albums Low and Heroes.
Rickman was a guest of the Berlinale several times. His films that appeared at Berlin included Snow Cake (2006) and Close My Eyes (1991).
"His ability to transform himself, his artistry in playing ambivalent characters and his distinctive voice made Alan Rickman a great actor," said Kosslick.
Italian filmmaker Ettore Scola, who died in January, aged 84, will also be honoured at Berlin with a screening of his 1983 film Le Bal.
"Ettore Scola was a master of Italian comedy, a social critic who observed everyday life with intelligence, wit and political acumen," Kosslick said.
The Berlin International Film Festival runs from 11-21 February.
The Berlin International Film Festival is to pay tribute to David Bowie and Alan Rickman with special screenings later this month.

Wintry weather affected travelling conditions earlier this year.
In February, lorry driver Andrew Raeside, of Kirkintilloch, died after his cab plunged 40ft (12m) from a bridge into a loch.

More than 100 people were injured in the truck bomb attack in the western city of Zliten, the deadliest since the 2011 fall of Muammar Gaddafi.
IS also said it killed seven people in a separate suicide bomb attack on Thursday at the oil port of Ras Lanuf.
Libya has descended into chaos since the overthrow of Gaddafi.
In a message sent via an online messaging system frequently used by IS, the group said its Tripoli wing were responsible for the attack in Zliten.
Islamic State militants have been attacking Libya's key oil terminals in the area around Ras Lanuf for the past week.
Firefighters were still trying to bring under control blazes at seven giant fuel tanks that were set alight by IS shelling on Thursday in nearby Sidra, officials said.
The group is present in several Libyan towns, including the eastern town of Sirte, Gaddafi's hometown.
Meanwhile, Egypt's foreign ministry says it is investigating reports in local media that 21 Egyptians have gone missing in Libya and may have been abducted by IS militants.

IS' assertion that it was behind the attack does not come as a surprise, but it will confirm fears of the group's wider reach in the country.
The attack also signals the group's long-term ambitions to extend its influence in Libya, especially as it comes under increasing pressure from bombing campaigns by the US-led Western coalition in Iraq and Syria.
Observers have been quick to point out that IS is now employing a strategy similar to the one used in the past by al-Qaeda in Iraq: targeting police and army training centres to create fear and prevent the rebuilding of state security institutions.
Libya has had no proper army or police force for the past four years.
This new grim reality is only likely to be reversed if the competing militias who rule the country come together to fight against IS.
There are signs that Libya's rival groups are starting to realise that they face a common enemy, but they are still a long way from presenting a unified front.
Funerals for those killed in the attack have been held in Zliten, 60km (40 miles) west of Misrata.
The country has been split into areas run by two governments - only one of which is recognised by the international community.
In December, rival politicians signed a UN-brokered deal to form a unity government.
In a surprise, unannounced move, the newly-appointed and internationally-backed presidency council travelled to Zliten on Friday night to pay their respects to the families of the victims.

The Islamic State group (IS) says it was behind a bomb attack which targeted a police training centre in Libya on Thursday, killing at least 65 people.
