The moral values group called for its members to protest JCPenney when the retailer hired DeGeneres as a spokesperson in February.
JCPenney ultimately chose not to act on the boycott and stood by DeGeneres as its spokesperson.
One Millions Moms director Monica Cole has announced that the organisation feels it has sufficiently convinced its members not to shop at JCPenney and will no longer actively pursue the boycott.
"We have heard back from so many of our members. We have heard back from men and women - not just mums - saying they will no longer shop there at JCPenney, as long as Ellen DeGeneres is their spokesperson," Cole told One News Now.
Cole added that One Million Moms still condemns JCPenney's choice to hire DeGeneres even though the group will now be focusing on other issues.
"JC Penney stated that Ellen DeGeneres shares the same values that they do," the group's director said. "So obviously, it's not the same as Christians or conservatives, which is unfortunate [because] JC Penney was founded by a Christian man."
DeGeneres responded to the controversy in early February, when she told her talkshow audience she was "proud" that JCPenney had chosen to stand by her.
"Here are the values I stand for - I stand for honesty, equality, kindness, compassion, treating people the way you'd want to be treated and helping those in need," DeGeneres said at that time. "To me, those are traditional values. That's what I stand for."
