A fishing line entanglement prevention device for preventing entanglement of weight line and bait lines includes a splitting member having a tubular vertical arm defining a vertical arm channel and a tubular lateral arm defining a lateral arm channel. The lateral arm channel is in communication with the vertical arm channel. A weight line bracing member includes an arm portion having a top end coupled to the splitting member and a bottom end, the arm portion defining an opening adjacent the bottom that is capable of receiving the bait line. The weight line bracing member is configured for selective insertion into the lateral arm channel. The bottom end of the arm portion of the bracing member defines a slot capable of engaging the weight line when the bracing member is inserted into the lateral arm channel.
