The gay community has a stronger voice than ever before, the Equality Commission has said.
But chief commissioner Michael Wardlow also said more must be done to protect the rights of lesbian, gay, bisexual and transgender (LGBT) people.
In a message ahead of the Pride parade, he said there has been a gradual increase in equality and respect.
"Earlier this year we saw the lifting of the lifetime ban on blood donation by gay men and we've also seen the strength of public opinion in favour of equal civil marriage," he said.
"The commission is hopeful that the long-awaited Sexual Orientation Strategy will be progressed as part of the implementation of the executive's Programme for Government."
Belfast Pride is now one of Ireland's largest LGBT festivals with 100 events reaching an audience of more than 50,000 over 10 days.
Christian groups are expected to stage two protests ahead of today's parade today.
Free Presbyterian minister Rev David McIveen said around 40 people are due to take part in a picket at Waring Street, with more attending a separate protest outside Belfast City Hall.
