The build-up to the 22nd Winter Olympics has been overshadowed by fears over security and human rights -- with a law passed last year banning the dissemination of "gay propaganda" to minors criticised by activists as vehemently homophobic.
Speaking as sporting action got under way at the Games on Thursday, Ban told a session of the International Olympic Committee in Sochi that everyone should join together to battle against discrimination.
"We must all raise our voices against attacks on lesbians, gays, bisexual, transgender or intersex people. We must oppose the arrest, imprisonment and discriminatory restrictions they face," he said.
"I know principle six of the Olympic Charter enshrines the IOC's opposition to any form of discrimination.
"Hatred of any kind must have no place in the 21st century," said Ban, who did not specifically address the situation in Russia.
Ban's comments came as more than 200 leading international authors including Salman Rushdie, Margaret Atwood and Jonathan Franzen criticised Russia's anti-gay and blasphemy laws as a "chokehold" on creativity in an open letter published in Britain's Guardian newspaper.
And Russian punk protest group Pussy Riot defied President Vladimir Putin by calling for a "Russia that is free" at a star-studded New York concert where they were feted by Madonna and cheered by thousands.

In a statement, the Department of Homeland Security said that "out of an abundance of caution" it regularly shares relevant information with partners both at home and abroad.
"While we are not aware of a specific threat to the homeland at this time, this routine communication is an important part of our commitment to making sure we meet that priority," it said.
Suicide bombings in the southern Russian city of Volgograd in late December killed 34 people and raised fresh concerns about the ability of the Russian authorities to ensure security during the Games, taking place close to Russia's restive Northern Caucasus region.
Russian security forces are still fighting Islamist insurgents in the Northern Caucasus and militants have threatened to strike targets in Russia during the Games.
About 40,000 members of the Russian security forces are on duty in an around Sochi during the Games in one of the tightest operations ever mounted at an Olympics.
The Games are the biggest event that Russia has hosted since the fall of the Soviet Union and the project has been championed by Putin ever since the successful bid in 2007.
Friday's opening ceremony will be attended by more than 40 heads of states including Chinese President Xi Jinping and embattled Ukrainian President Viktor Yanukovych, who is facing protests at home.
