The New Commandment is a term used in Christianity to describe Jesus's commandment to "love one another" which, according to the Bible, was given as part of the final instructions to his disciples after the Last Supper had ended, and after Judas Iscariot had departed in John 13:34.

Little children, yet a little while I am with you. Ye shall seek me: and as I said unto the Jews, Whither I go, ye cannot come; so now I say to you. ³⁴ A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. ³⁵ By this shall all men know that ye are my disciples, if ye have love one to another. —John 13:33–35 (KJV; emphasis added)

This commandment appears thirteen times in twelve verses in the New Testament. Theologically, this commandment is interpreted as dual to the Love of Christ for his followers. The commandment can also be seen as the last wish in the Farewell Discourse to the disciples.

The statement of the new commandment by Jesus in John 13:34–35 was after the Last Supper, and after the departure of Judas. The commandment was prefaced in John 13:34 by Jesus telling his remaining disciples, as little children, that he will be with them for only a short time, then will leave them.

In the commandment Jesus told the disciples: "Love one another; as I have loved you".

Just after the commandment, and before the Farewell Discourse the first reference to Peter's Denials took place, where Jesus predicted that Peter would deny him three times before the cock crow.

Two similar statements also appear in chapter 15 of the Gospel of John:

The Johannine writings include other, similar passages.
