Mayor de Blasio plans to march for the first time in this year’s St. Patrick’s Day Parade.

The mayor has boycotted the historic march because its organizers excluded groups from walking behind gay banners.

De Blasio will likely march twice at the parade — joining the NYPD at the front of the march and later appearing with the Irish gay group Lavender and Green Alliance, the Irish Voice reported Wednesday.

Lavender and Green said it asked de Blasio to march with the group on March 17 as well as the earlier St. Pat’s for All Parade in Woodside, Queens, on March 6.
