How can an unconfirmed transaction be removed from the memory pool?

Question

Using Bitcoind and Json-RPC, how can I remove an unconfirmed transaction from the memory pool?

The scenario being that I want to remove the unconfirmed transaction because it's not getting confirmed, and it's preventing me from sending new transactions spending the same inputs because Bitcoind considers it a double spend.

Try the removeprunedfunds RPC command. It

deletes the specified transaction from the wallet. … This will effect wallet balances.

don't know why you're voted down.. that did it for me – tobi Jun 14 '18 at 09:43
This is correct, but it should be noted that `removeprunedfunds` will remove the tx from just the local node's mempool and not necessarily from the mempool of other nodes that the tx may have propagated to. – A-Diddy Oct 04 '21 at 17:22

There is no RPC command available to remove objects from the mempool.

Not really. Removal from wallet and removal from mempool are two distinct operations. – Jan Matějka Sep 17 '20 at 16:18

I haven't found a good way to clear just a single transaction from the mempool, but you can shutdown bitcoind and then delete ~/.bitcoin/mempool.dat and clear the entire mempool, and then restart bitcoind
