The meeting at SP headquarters here was attended by Akhilesh, his uncle Shivpal Yadav, senior leader Azam Khan and party office bearers.
However, there was no decision as to who will be the Leader of the Opposition.
The meeting of the newly elected MLAs, which comes after the SP's rout in the polls, also decided to hold the party's national executive meet on March 25.
"We have authorised party president Akhilesh to decide on the name. The party's national executive will meet on March 25," SP MLA Parasnath Yadav told reporters.
SP, which had 224 MLAs in the outgoing House, won only 47 seats this time in the 403-member House.
Having emerged as the largest opposition party, the leader of SP Legislature Party will also be the Leader of the Opposition by default.
SP spokesman Rajendra Chowdhury said Akhilesh congratulated the newly elected MLAs for winning elections in the "adverse scenario".
"When the PM and the BJP national President were trying to mislead and gag voice in democracy during elections, SP won 47 seats," Chowdhury said, adding that some MLAs also raised the issue of alleged EVM tampering and demanded that future elections be held using paper ballots.
Shivpal and Azam held a closed-door meeting for over half an hour.
During the elections, Shivpal was not included in the star campaigners' list and he remained limited to his constituency Jaswant Nagar (Etawah).
Besides, Shivpal and Azam, party leader Ram Govind Chowdhury's name was also being considered for the post, party sources said.
Last week, Shivpal had tweeted a video "hum ladengey aur milkar phir jeetengey (We will fight again and win together)".
As a member of Legislative Council, Akhikesh might take over as the LoP in the Upper House, replacing senior MLC Ahmed Hasan, who is presently holding the post.
