Communist Party of Nepal (Burma) (Nepali: नेपाल कम्युनिष्ट पार्टी (वर्मा)), initially known simply as Communist Party of Nepal or Communist Party of Nepal (Rayamajhi Group), was a communist party in Nepal. The party emerged from a split in the original Communist Party of Nepal in 1962, representing the pro-Soviet sector of the party. Its main leader until 1983 was Keshar Jung Rayamajhi, who had been the general secretary of the original CPN.
In 1966 the group organised a 'Third Central Conference', with delegates from 17 districts. The conference amended the old CPN party constitution, adopting 'National Democracy' as the line of the party. The conference stated that the royal takeover in the country had been a backlash for the democratic forces, and called for a united front to be formed with Nepali Congress. Moreover, the conference made a call for the holding of a party congress.
In 1967 the group held its 'third congress' in Kathmandu (considering the two first CPN congresses as theirs). The congress elected a 21-member Central Committee and a five-member politburo. The politburo consisted of Keshar Jung Rayamajhi (general secretary), Bishnu Bahadur Manandhar, Krishna Raj Burma, Kamar Shah and Krishna Prasad Shrestha. Manmohan Adhikari and Shambhu Ram Shrestha, both in jail at the time, were nominated to the Central Committee. The congress stated that the Soviet Union was the international centre of socialism, and condemned the positions of China. The congress called for a peaceful political struggle in Nepal, and condemned the idea of armed struggle as 'adventurism'. The congress branded the rival CPN of Tulsi Lal Amatya and Pushpa Lal Shrestha as 'extremist'.
